Perfect sous vide pork belly, why is the bottom part always tough?

Recommended Posts

I'm trying to cook the perfect melt in your mouth pork belly. I've done sous vide, but still find the bottom part(dark part of meat) dry and stringy. Any tips?

I always test it without any sauce so I can check for moistness and tenderness, and always get the best pork.

I've tried 181F 12 hours, 171F 12 hours, 171F 10 hours.

Does anyone have any good temp and time recommendations?

I don't like the 135F 48 hours because I find the fat too firm and not melt in your mouth.

I've done MC's 140F/72 hour and it was ridiculous. The fat is very delicate at this point, and the whole thing melts in your mouth.

First of all, I'd look into the quality of the meat you're purchasing. Maybe buy it from somewhere else just to see if that makes a difference.

Anyway, like KennT I'm a fan of Modernist Cuisine, altho' I've come to settle on the method prescribed in the 'Sunday pork belly recipe'. That is, to say, brined and then (after a good rinse and dry) 62C/40 hours without the skin. As for the skin, I scrape off as much of the fat as possible (you don't need to get it all--don't stress over the fat that smears like poop on a blanket rather than comes off cleanly) then salt it a little with coarsely ground salt and then park it, in little chunks, on a rack in a 70C oven for 5 hours. Remove it. Crank the temperature to a blistering 220C. Park the rack and a pot of water in the oven for 10-15 minutes until the skin is crisp. See my Christmas dinner from last year. The meat wasn't stringy at all.

To get it 'perfect' it's also important to trim off any excess lumps of fat. If you were slow-roasting, say, a thick layer of fat in between the skin and meat would be acceptable. When you cook it sous vide that stuff isn't going to render off and will just be a jelly. Lose that.

I always use 10 hours at 80C and it turns out so tender that it is almost impossible to slice without shredding it. After pressing and chilling it slices better but still borders on falling apart.

I generally cook it marinated, the favourite being Vietnamese caramel.

I've done the 10 hours at 80C, but find that the meat winds up drier than it does at 60degC.

I also cook it skin off, but I'll take the skin, boil it (or even better pressure cook) in salty water until it's almost falling apart tender- you have to be very careful when taking it out of the pot so it doesn't tear. Let it cool on a rack, and when at room temp, scrape all the fat off with a butter knife or spatula... then dehdrate in a 250degF oven until it's hard and looks like a shrinky-dink. At you can then put it in 375degF oil and it puffs very well.

Thanks for the tips Chris,

I'm a perfectionist, so at 171F 12 hours MOST of the meat is meltingly tender. What I'm talking about is the meat at the bottom part. Usually there is 3 or 4 layers of meat, and I'm talking about the very bottom layer that is dark colored. That's the part that is dry and stringy. Have you had issues with this bottom part?

Based on the fact that (in my limited experience) I have never heard about this, and had never encountered the same situation in my pork belly cooking, I think it might not have anything to do with your cooking.

It is possible that when the meat was packaged, it got dried out. Once the meat is dried out like jerky, it is not easy to make tender again.

A couple times, yeah. Hence my initial comment about maybe buying your meat somewhere else. Assuming you have a choice and all. Me, I can buy it from the supermarkets and most of the local butchers (basically any butcher that isn't, say, halal). So there's a fair bit of choice. I understand that pork belly isn't so readily available in other places.

If you have no choice at all, not without ordering online/driving crazy distances, see if 12 hours or so in a brine helps.

Sorry but I have never encountered this sous vide. Is it some of the rib membrane left attached? I always trim mine to remove it.

You should be able to sear the skin to crisp it up. Works with moist-cooked chicken, salmon, duck confit ...

Depending on how it was cooked SV (time/temp), the skin may not be fully tenderized.  But, if it was fully tenderized, I have seared on a very hot cast iron pan (I was doing lots of small pieces at once, so it acted like a plancha) and it seared nicely - I even got the skin to puff a bit which was nice.

Winners will be drawn at random from those posting pictures and descriptions of their completed loaves. Complete rules and other details can be found here.
       
      For part two, we're featuring another cornerstone recipe from the book: Direct Country-Style Bread. The only leavener here is instant yeast, so production time is considerably shortened. The relative lack of flavor compared to long-proofed doughs is offset by the use of whole grains. Courtesy of The Cooking Lab, here's that recipe (extracted from the book and reformatted for purposes of this contest):

      Thanksgiving is around the corner, and I think I have a plan.
      I was keen on cooking the turkey sous vide, but have been vetoed by my a family member- "you can't feed grandma that bacteria-laden turkey! it never got hot!"
      I've tried to explain the process, and the safety, but I conceided. I'm cooking for a bunch of traditionalists, so I'm trying to keep it interesting, yet familiar and not too out of the box.
      I think I may have a more interesting plan now anyway.
      It goes like this-
      Break down the bird (from my CSA with Allandale Farm in Boston, MA, removing the breast skin in-tact
      break down the carcass, pan-roast it, and make stock.
      Make a tenderloin by stacking the breasts and glueing with Activa RM, and wrapping with the skin.
      two questions on this front:
      How long can the rolled "tenderloin" sit before cooking- can I roll it out 24 hours before showtime?
      Is there a decent way to add some flavor between the breasts- chopped sage/thyme, etc. or will this negatively affect the process? Will it cook OK?
      Braise the dark meat, following this Daniel Boulud recipe (ish.)
      Confit the wings. I currently have a test batch curing overnight, rubbed with a ton of salt, thyme, bay leaf, clove, tellicherry peppercorns, garlic, and some juniper. Picked up 7.5# tub of Hudson Valley Foie Gras duckfat for the cook.
      In addition, I'm going to do some truffled mashed potatoes, butternut squash soup with some smoked duck breast, and some veg- brussel sprouts, and something to keep the kids happy. Also pondering family-style (really partner-style) mac and cheese in some very small le crusets, following the Hattie's recipe.
      Is it worth brining the bird?
      I'm looking for reactions to this plan, and any improvements possible, or a good old-fashioned critique.
      Thoughts?

      Figured I don't need to dump all this into the contest thread - so I'll post here.  My journey to making my first MC loaf.
       
      Her's the poolish after >12 hours:

       
       
      Not pictured - water with yeast in it below the bread flour and poolish

       
      That went into the mixer and not long later I had a shaggy mass:
       

       
      That rested for a while - then mixed until medium gluten formation - a window pane that was both opaque and translucent (no picture for that slightly messy part)
       
      Folded and rested, folded and rested, I think this is 1/2 the mass now ready to rest one final time.
       

       
      Proofed it in the oven - I have a picture of that but it's just foggy window oven
       
      Then it went into the oven, here it is at max temp - 450 with steam turned on.

      For our first recipe, we're starting with a cornerstone recipe from the book: French Lean Bread. I've personally made this one and it's both delicious and completely approachable by anyone with an interest in this book. Courtesy of The Cooking Lab, here's that recipe (extracted from the book and reformatted for purposes of this contest):
       





       
      The recipes in this book tend to rely on information presented more extensively earlier in the books, so if anything isn't clear enough here please ask and Dave and I will do our best to answer your questions (we've had early digital access to the books for the last month or so).

      I thought that I had read that if you SV in bulk, and the freeze, that you were supposed to SV the item again based using the same time in the bath as when you first cooked the item. I tried SVing 4 meals's worth of pork strips and froze 3 of the 4. When I re-SV'ed a package last night (at a slightly lower temp to not increase the doneness, they were borderline dry, way different than the first package right out of the bath.  What am I missing?
