Paleo Eats: 9/7/12

Pin It

With my family snoozing away, I doled out drugs at the hospital until 4 a.m., when I paused to eat my packed leftovers: pressure cooker lamb shanks, collard greens, and bone marrow.

For dessert, I enjoyed some fresh cherries and coconut milk before finishing my shift.

Blinking away the sunlight, I made it home just in time to kiss Big-O before he trotted off to school with his dad. Lil-O, our resident Lego maniac, built me some colorful (albeit less than aerodynamic) airplanes while I packed his lunch for preschool.

As I’ve mentioned, my younger son insists that we pack him the same lunch every day: eggs, fruit, and carrots. He’s like a machine.

I had a few minutes to spare before I had to drive Lil-O to preschool, so I grabbed two sirloin roasts from my trusty defrost bowl in the fridge…

…seasoned them with Penzeys Spices’ Greek Seasoning and kosher salt…

…vacuum-sealed the beef, and dunked the packets in my SousVide Supreme (8-12 hours at 130°F for medium rare).

With the meat submerged in the countertop jacuzzi, I deposited my little guy at school and face-planted into bed.

By the time I woke up, the roasts were perfectly cooked. The only remaining task was to whip up a couple of vegetable sides, so I threw a tray of seasoned broccoli florets in the oven and washed a bunch of ripe tomatoes that came in my CSA box.

I scattered the chopped tomatoes on a plate and seasoned them with aged balsamic vinegar, extra virgin olive oil, fleur de sel, and freshly ground pepper.

Normally, I’d add a basil chiffonade and some minced shallots to the tomato salad, but I didn’t have any on hand. (Heck, in a perfect world, someone else would be cooking dinner and I’d be catching up with my favorite housewives on Bravo, but I digress…)

Once the vegetables were ready…

…I fished the two sirloin roasts out of the SousVide Supreme. 

I dunked one of the roasts in an ice bath and I seared the other one in a smoking-hot skillet greased with ghee

…until the juicy roast developed an even char.

I thinly sliced the sirloin…

…and hollered at everyone to sit down for dinner.

Here’s what our dinner looked like:

I love the convenience and idiot-proof nature of sous vide cooking, and think it’s great that more home cooks are trying it these days. I even saw on Instagram that one of my favorite kitchen cavemen, George Bryant, has joined the party.

Sure, a SousVide Supreme ain’t cheap, but remember: You can hack your own water oven for just a few bucks. So if — like me — you’ve considered the food safety stuff and want to give sous vide cooking a shot, get yourself a beer cooler and a thermometer, and let me know what you think!

Sous Vide Grass Fed Shredded Beef Chuck Roast

Pin It

Chuck roast isn’t normally my favorite cut because it can get powdery and stringy by the time it finally tenderizes. Enter the magical water oven to the rescue! I’ve found that with a little bit of seasoning and a long soak in the SousVide Supreme, you can get a big pile of tender and moist shredded beef with almost no work at all. To make it even fancier, you can toss the beef with your favorite Paleo-friendly jarred marinara sauce and you’ve got a dish that will please your whole cave.

Ingredients (feeds 6-8 people):

  • 3.5 lb grass fed chuck roast, tied 
  • Kosher salt
  • Freshly ground pepper
  • 1 tablespoon of ghee or fat of choice
  • 8 ounces cremini mushrooms, sliced thin
  • 12-24 ounces of your favorite marinara sauce (I like Rao’s and Lidia’s)

Season the roast liberally with salt and pepper…

…making sure to coat all sides.

Vacuum seal the roast…

…and dunk it in a SousVide Supreme set at 160 F.

After 24 hours (and up to 36 hours), remove from the cooked roast from the water oven…

…pat it dry…

…and attack it with two forks.

Melt the ghee in a large sauce pan or dutch oven over medium heat. Add the mushrooms and saute until the liquid has evaporated (6-8 minutes). Season with salt and pepper to taste.

Pour in your favorite marinara sauce and bring to a simmer. How much you add depends on how saucy you like your beef.

Toss in the shredded chuck and dig in.

Cooking Sous Vide: Plastic Safety

Pin It

You know I love cooking sous vide.

Despite my hectic work schedule and parenting duties — not to mention daily food blogging! — I’m still able to whip up healthy, tasty, perfectly-cooked meals with minimal prep time, thanks in large part to my SousVide Supreme. It’s one of my go-to kitchen appliances, and I’ve developed a number of recipes that call for vacuum-sealing various proteins and dunking them in my temperature-controlled water bath.


So naturally, I was alarmed to read Chris Kresser’s recent post about a new study that shows that most plastics — including many that are BPA-free — can leach out chemicals with estrogenic activity (EA). In the study, researchers tested over 500 plastic products available to consumers — including baby bottles, tupperware containers, sandwich bags and plastic wraps — and found that virtually all of them leached chemicals that “produce an increase in circulating estrogen, which in turn can cause problems such as early puberty in females, reduced sperm counts, altered function of the reproductive organs, obesity, increased rates of certain cancers and problems with infant and childhood development.” 



But that’s not all. Chris is an avid sous vider, and has been using reusable plastic bags to seal his food for cooking — so he had a special note of warning for his fellow sous vide fans:

After reading this study, I’m feeling very uncomfortable about the idea of eating anything that comes out of a plastic bag that has been sitting in a hot water bath for several hours. This is a crushing blow, as I love cooking with the Sous Vide. But in light of the evidence that even BPA-free plastics bags leach chemicals with EA even without added stress like a hot water bath, I think erring on the side of caution is probably wise.

Double yikes.

This isn’t the first time I’ve heard of concerns about cooking foods at low temperatures that have been vacuum-sealed in plastic, but a number of food science gurus, including Harold McGee and Nathan Myhrvold, have given sous vide cooking a big thumbs-up — provided the proper materials are used for vacuum sealing. But none of ‘em had squarely addressed the EA-leaching issue that Chris raised.

My initial reaction? Crap. I can’t sous vide anymore. When it comes to Paleo science geekery, Chris is one of my favorite and most trusted resources, so when he talks, I listen. And in light of my mother-in-law’s recent bout with a form of estrogen-fueled breast cancer, Chris’s words of warning freaked me out.


Still, given my ardor for sous vide cooking, I wasn’t about to give it up without exhausting all options. Once the initial shock of Chris’s post wore off, I sprang into action.

I did some serious digging, y’all. And luckily, I learned that there are some bags on the market that are indeed safe for sous vide purposes, and pose no problems from a BPA or EA perspective. The key is to stick with vacuum bags that are free of BPA, phthalates, and other plasticizers. It’s the plasticizers — chemical additives like phthalates that increase the pliability and fluidity of the plastic — that contain EA. 

I was able to confirm, for example, that Jarden’s FoodSaver bags are made from polyethylene glycol and nylon, and don’t contain BPA, phthalates, or other plasticizers with EA-leaching additives.


Last year, Richard Nikoley shared this quote from an email list, noting that there is “absolutely zero danger” in cooking with FoodSaver bags:

The plastic that touches the food is made of 100% polyethylene, contains no plasticizers or estrogen-like compounds. The FoodSaver bags are 5 layers of polyethylene with an outer layer of nylon. While you might get BPA from your cans of coconut milk, there is simply no BPA that will get into your food from sous vide. 

The temperatures of sous vide are also low (polyethylene doesn’t begin softening until 195F), although I would imagine that a very small amount of polyethylene would still make it onto the surface of your food through diffusion. Polyethylene, however, is considered biologically inert, and scientists have been unable to detect any toxicity in animal tests (unlike BPA). It passes the Ames test and other studies of damage to DNA, and doesn’t have a similarity to estrogen. 

At this point, I’m unaware of any evidence at all that polyethylene poses any harm. As always, it’s up to you, but for me the taste and health benefits (less AGE production, nutrient loss, and protein degradation, and more retention of fatty acids) that sous vide provides far outweighs what seems to me to be an almost arbitrary possibility that it will harm me.


I also reached out to Dr. Mary Dan Eades — the mother of the SousVide Supreme herself! — for her take on the EA issue. She, too, pointed out that the estrogenic additives in plastic “generally comes from the various phthalates and BPA” — neither of which are contained in the bags made and sold by her company. Dr. Eades continued:

[O]ur quality assurance testing on the plastics used in our cooking pouches involves stressing for 4 hours at boiling (which is never the cooking temperature in sous vide anyway) in migration studies using alcohol, olive oil, and distilled water in the pouches to simulate different types of foods that would be cooked. The results were that plastic components were not found to migrate into the food simulants even under stressed conditions.

Long story short: Both the SousVide Supreme pouches and the FoodSaver bags are perfect for quick, airtight vacuum-sealing, and it looks like both are also free of BPA- and EA-leaching issues. These pouches should be fine for sous viders who are concerned about minimizing prep time while maximizing food safety.

[UPDATED 1:30pm PST - Hold the presses! Stuart Yaniger, one of the researchers who published the study referenced above and a Vice President of R&D at PlastiPure, a company that certifies products as EA-free and thus “PlastiPure-Safe”, has commented below to offer an opposing viewpoint. According to Yaniger, EA can lurk in other additives as well, and thus no plastic or silicone products are truly safe “unless a manufacturer has developed the product specifically to be free of EA” (for example, PlastiPure-certified products). Please see his comment and my response below for more details.]


But what if — like Chris Kresser — you’re reluctant to purchase single-use vacuum pouches for sous vide purposes because of the environmental waste? As Chris put it, even if the plastic doesn’t end up hurting you, it all “ends up in a big floating island in the middle of the ocean somewhere.” Other folks have also written to tell me that they consider it incredibly wasteful and eco-unfriendly (not to mention expensive!) to use single-use vacuum bags or pouches for sous vide cooking. 

Well, I think we’ve found a solution that addresses both the EA-leaching risks AND the environmental concerns.

The answer? Food-grade silicone bags.


Fitbomb hit upon this solution and chatted with one of his workout buddies — Jackie Linder, the founder/CEO of LunchBots — about the possibility of using silicone bags for sous vide purposes. She, in turn, suggested that we check out Lekue’s reusable silicone food pouches (available on Amazon for $20 per bag). We looked into ‘em, and ordered some to try in our SousVide Supreme.

[UPDATE 9:55am PST - It looks like the clear Lekue bags are selling like hotcakes now! They’re temporarily out of stock at Amazon, but the green, blue, and red ones are still available.]


The verdict?

It works! (Well, with the one recipe we’ve tried so far, anyway!)


Yes, the silicone bags are thicker than typical vacuum-seal food pouches, so some recipes may require a bit of experimentation when it comes to cooking times. They’re not huge, so big or oddly-shaped foods may not fit. Additionally, manually squeezing/displacing all the air out of the silicone bags can prove a bit tricky and take some extra work. But these Lekue bags are dishwasher-safe, re-usable, and relatively inexpensive. So all you hippies out there can start sous viding guiltlessly!


Am I saying you should ignore what Chris Kresser has to say about EA leaching from most plastics? Not at all. He cites valid concerns about using plastic food and beverage containers and utensils, and since reading what he had to say, I’ve cleared my cupboards of all of our plastic bottles, cups and bowls, and replaced them with stuff from LunchBots and other makers of stainless steel and glass dinnerware. Yes, I realize that statistically, the health risks of using a plastic plate is nowhere near the risk of, say, getting into a car and driving to work — but there’s no reason to keep feeding my kids out of plastic receptacles when I could just as easily serve ‘em meals using glass or stainless steel containers.


Likewise, if you’re vacuum-sealing your food with plastic bags containing BPA and/or plasticizers like phthalates, you should switch to something else pronto. As I’ve described above, there are options out there that are perfectly safe for cooking sous vide.

One final note: In case you’re wondering, I’m not a paid shill for any of these products. Sure, I’ve gushed about my SousVide Supreme and guest-blogged for them in the past (for free), and I’ve purchased reams of FoodSaver bags from Costco and Lekue silicone bags from Amazon. But cross my heart and hope to die, stick a needle in my eye: I wasn’t asked by anyone to hype ‘em up in response to Chris’s post. If you end up buying any of these products from my Amazon shop, I get a small percentage commission, but that’s it. 

I’ve spent a TON of my own hard-earned dinero to buy all my kitchen tools myself (including my SousVide Supreme and various types of bags). I just love sous vide cooking, and want to use BPA- and EA-free pouches that are safe for my husband and kids.

After all, I’m not trying to kill them — even when they piss me off.

Sous Vide Grass Fed Beef Tongue ‘n Cheek

Pin It

Never in a million years would I attempt to cook grass fed beef tongue…

…or beef cheeks…

…without my SousVide Supreme.

Nowadays, I’ll confidently tackle any and all unusual slab of meat ‘cause the water oven will magically transform cheap, tough cuts of grass fed meat into tasty fork-tender braises. Yes, you’ve got to do some planning because it normally takes a couple days before the meat is ready to eat — BUT that’s all you need to do!

The prep work takes just minutes (season + vacuum seal) and you simply dunk the packets in the SousVide and forget about them. The only thing you have to decide is how you like your meat cooked — rare, medium-rare, medium, medium-well, or well-done. Plus, you can cook it ahead of time, ice it, and reheat when you wanna eat it. Totally a no-brainer.

Here’s what I gathered to make enough meat to feed 8-10 people:

Here’s how I made it:

I took out the beef tongue…

…and cheeks…

…dusted them with Chili 9000 seasoning, salt, and pepper…

…and vacuum sealed each packet with a pat of butter.

I plopped the sealed bags into the water oven set at 158 F and let them steep for 48 hours.

Two days later, I took out the meat and dried them off with paper towels.

I peeled off the outside of the tongue (ew!)…

…and trimmed away any stray taste buds and goo. (Yes, this part skeeves me out.)

I sliced the tongue crosswise into 1/2-inch pieces…

…before frying them in bacon grease over medium high heat.

The tongue “steaks” take a couple minutes to crisp on each side. 

After I plated the tongue, I sprinkled fleur de sel on each piece.

The beef cheeks were much less work. All I did was dry off each piece and sear them in bacon grease on each side. Then, I seasoned with salt and pepper and shredded the meat with a fork.

Both the tongue and cheeks were tender and delicious — perfect for lettuce-wrapped tacos or just as emergency protein.

It was the worst of times…and the worst of times. Okay, I’m being dramatic but keep reading if you dare.

Work was super busy again. So much so that I barely had time to eat the meal I packed: emergency protein, baked sweet potato fries, and sauteed bell peppers.

Things only got worse when I came home and discovered that our chest freezer in the garage was busted. 


I spent the next couple hours crazily cooking and packing since we had massive amounts of defrosted meat. We piled as much as we could fit into our main freezer, Fitbomb brought some bags o’meat to stash in his work freezers…

and I cooked off the remaining meat. I seasoned pork and goat chops with Spicehound’s seasoning salt

…vacuum sealed them…

…and gave my mom instructions to plop them in the SousVide Supreme later in the afternoon.

Then, I dumped some beef shanks, short ribs, carrots, onions, and a bay leaf into the slow cooker

…and collapsed into bed.

When I woke up in the evening, I took the chops out of the water oven and iced them.

(As a side note: THANK YOU to all our buddies who generously offered to house our meat! The silver lining of this mini meatastrophe is now I have a bunch of cooked food for future meals. Hooray!)

For dinner, I sauteed a head of escarole with shallots

…and adjusted the seasoning of the impromptu slow cooker beef stew before ladling it out.

Here’s my dinner plate:

After dinner, I exercised in the garage before I headed to work ONE LAST time this week. Hallelujah!

Here’s another video…

This time, I demonstrate how to use a SousVide Supreme to prepare a couple of 4505 Meats’ Cowboy Chops for a dinner party. Yeehaw!

The process I used to sous vide the rib-eyes was straightforward and simple; I seasoned the steaks the morning before the party, stored them in the fridge, and dunked them in the water oven the next morning.

We ended up serving just one of the gigantic chops because each was a whopping 2.5 pounds. I chilled one of the cooked steaks in an ice bath before storing it in the freezer. The remaining chop was seared on our gas grill before I evened out the char with my kitchen torch.

See? It really is like cheating when it’s so easy!

Every nightshift is blending into the next…

Luckily, I see the light at the end of my seven-night stretch!

For my meals at work, I chowed on some leftover frittata, sauteed shrimp with onions and cherry tomatoes, and roasted broccoli and cauliflower.

When I got home from work, I quickly seasoned some pork chops with Volcano Grind seasoning

…vacuum-sealed and stored them in the fridge…

…and then I took the Double-O’s to school.

I came home, filled and preheated the SousVide Supreme to 134 F, gave my mom instructions to dump in the pork chop packets mid-afternoon, and hit the hay.

When I woke up in the evening, I stir-fried a batch of Asian cauliflower fried rice with leftover Kalua pig, bell peppers, carrots, shredded spigarello, and herbs…

…and charred the sous vide pork chops with my kitchen torch.

Here’s my dinner plate:

After dinner, I practiced some snatch balances in the garage and hurled a medicine ball against the wall before heading to work.

Just one more night to go!

Sous Vide Black Cod Fillets

Pin It

True confession: cooking seafood always stressed me out in the past. Maybe it’s ‘cause proteins from the sea are extremely perishable and seem to overcook in an instant. Plus, have you seen the price of high quality seafood lately?! Marone!

For many moons, my tame kitchen adventures involving fruits de mer only revolved around salmon and shrimp…but not anymore!

Armed with a SousVide Supreme and the conviction that I gotta get more healthy omega-3’s in my belly, I jumped in the deep end and joined a seafood CSA. I’m excited and a tad nervous that we’re getting a weekly delivery from Siren SeaSA — a sustainably-harvested local seafood CSA in the San Francisco Bay Area — but I’m ready for a challenge!

For my first delivery, I received two be-YOO-tiful black cod fillets.

Wanna see how I sous vided them?

Holy moly! The past 24 hours were busy, busy, busy!

I ate two meals at work and the first one was very similar to yesterday’s packed lunch: sliced cucumber, bell peppers, and organic roast beef slices topped with Aubergine dip. I also devoured some coconut butter and a square of dark chocolate. Try as I might, I can’t seem to kick my cacao addiction. 

Right before I left work, I ate a packet of Chipotle SeaSnax and the last box of emergency protein and mixed veggies.

When I got home, we shot some family portraits…

…walked Big-O to school, and hustled Lil-O to his first day of preschool (the family portraits were his first homework assignment).

After attending a MovNat Fundamentals session, I’ve consciously incorporated more lifting and carrying of asymmetric loads in my daily life. As a result, I’ve been clean and jerking my kids and carrying them on my shoulders A LOT.

Lil-O’s first day of preschool was only 75 minutes long but he had SO MUCH FUN playing and exploring!

He was sad to leave but I reassured him that the two of us would be back on Thursday for a full morning of play (I’m volunteering at the co-op every other Thursday).

Before I hit the sack, I peeked in on the short ribs that were hanging out in the SousVide Supreme…

…and then promptly conked out.

I woke up in the evening and started dinner prep in earnest because we were in a rush to attend Back To School Night at Big-O’s school.

Since the short ribs were ready to be eaten, I roasted a tray of curried cauliflower

…and threw together a quick tomato salad.

I removed the short rib packets from the water oven and put one of them on ice for later consumption…

…and charred the other pieces with my kitchen torch.

Here’s my dinner plate:

After dinner, Fitbomb and I ran to Big-O’s school to meet his teacher and mingle with the other parents. Upon our return, I did a little bit of exercise in our garage gym before heading to the hospital for my last night of work for the week. Hooray!

Yay! I’m more than halfway through my workweek!

At the beginning of my nightshift, I noshed on a grass fed PaleoKit and a small container of coconut butter.  

Six hours later, I ate my last meal at work:leftover porktastic meatloaf with sweet potato fries and green beans.

And, no, my squashed leftovers that were manhandled during transit didn’t look as appetizing as this plate but they still tasted good.

When I got home, I seasoned four pounds of short ribs from U.S. Wellness Meats with Spicehound’s Thai Coffee Rub (this spice blend’s not 100% Paleo-friendly, but I’m okay with using it occasionally) and vacuum-sealed them.

 Then, I filled and preheated the SousVide Supreme to 140 F and dunked the ribs in for a couple days. Yes, you read that right – they need to soak for a minimum of 48 hours.

After I tidied up the mess I made in the kitchen, I hugged my boys, and went to bed. I continued reading the first hundred pages of Primal Body, Primal Mind before falling asleep.

While I napped the day away, Fitbomb and the kids hung out with Dr. HA and her crew.

Yes, I’ll admit that it sucks to work every other weekend.

When I woke up in the evening, the boys and I drove to The Patty Shack to meet my parents for dinner.

This time we ordered the same items that we tried on our first visit:

Roasted Brussels Sprouts…

…sauteed asparagus…

…and I got a bun-less midnight burger sans cheese with extra patty and avocado.

This burger was so hefty…

… I actually packed up the extra patty and leftover veggies for a work meal that I’ll chow on later this week.

Next time, I probably won’t order the sprouts or bacon (gasp!) because both are pretty sweet. All in all, I really enjoyed our tasty al fresco meal.

Afterwards, we came home and got the Double O’s ready for bed. Before jetting off to work, I practiced some pistols, double-unders, wall balls, and did workout #17 from my Everyday Paleo book. Only three more nights of work!
