What Are You Cooking Sous Vide Today? (Part 3)


Recommended Posts

A cousin of mine and his wife came for a visit a few years ago from Holland.  They couldn't believe the size of the meat portions they were served in restaurants.  It was way more than they were used to.

It's an old school steakhouse thing (e.g, Peter Luger's) typically done on cuts that are big/thick enough to be shared (which this was, even though I was the only person eating it). It also helps distribute the sauce evenly. And it lets you eat the meat from the rib bone whenever you please instead of waiting until the end.

OK, but look at all the moisture loss, Theres a pool. How is this something to want?

OK food scientists out there, here is a question slightly out of left field.



When you cook say beef  sous vide, at various temperatures there are various reactions ( https://douglasbaldwin.com/sous-vide.html#Safety ....Muscle meat is roughly 75% water, 20% protein and 5% fat and other substances. The protein in meat can be divided into three groups: myofibrillar (50–55%), sarcoplasmic (30–34%) and connective tissue (10–15%). The myofibrillar proteins (mostly myosin and actin) and the connective tissue proteins (mostly collagen) contract when heated, while the sarcoplasmic proteins expand when heated. These changes are usually called denaturation.

During heating, the muscle fibers shrink transversely and longitudinally, the sarcoplasmic proteins aggregate and gel, and connective tissues shrink and solubilize. The muscle fibers begin to shrink at 95–105°F (35–40°C) and shrinkage increases almost linearly with temperature up to 175°F (80°C). The aggregation and gelation of sarcoplasmic proteins begins around 105°F (40°C) and finishs around 140°F (60°C). Connective tissues start shrinking around 140°F (60°C) but contract more intensely over 150°F (65°C).)


My question is if the temperature is taken above these temperatures but later returned to these temperatures does the reactions still apply.


Example: If I was to heat meat to 80c (to cook vegetables or sauce for example) then return the temperature to say 55c, will "....aggregation and gelation of sarcoplasmic proteins..." start to occur (or reoccur)?

I do understand any compression or shrinkage (and expelling of water) is probably not reversible.

The reaction the respective components of your item undergo are irreversible and will occur at said temperatures.


To stay with your example: If you take a piece of meat and drop it into a 80 oC bath it will reach the 55 oC internal temperature on its way to the target temperature, and said reactions will occur. Returning later to the lower temperature will not alter the result, as the reaction will have reached completion.


If the overall time above 55 oC (e.g. at 80!oC) however is insufficient and does not allow the reaction to come to completion, then a return to 55 oC will drive the described reaction to completion. In the extreme, think searing meat, were you expose the meat to very high temperatures for very short time, thus leaving most if the interior unaffected by these temperatures.

      I'm looking to buy some new pots and pans and would like to tap into your knowledege and experiance with them. Which pans tend to yield the best and most consistant results. Same for pots. Any and all recommendations would be greatly appriciated, thank you in advance.

      Has anybody tried making a dark roux in a pressure cooker? Can this be done without scortching do you think? I have made roux in the oven before and started wondering about this topic.

      I really want to improve the flavor of my chicken breast so I want to try to inject brine with fat and flavors.
      I would like to try brining with some hydrocolloids. The one example I found is this: https://torontofoodlab.com/2013/08/20/meat-tenderizing-with-a-carrageenan-brine/.
      However I cannot apply that to my chicken breast because I am cooking it sous vide, so the chicken will not reach the temperature needed for the carrageenan to gel.
      I am thinking of using Methyl cellulose, first disperse in hot water, then leave it for 24 hours in the fridge, then add salt, fat and flavors and inject it.
      I am afraid that until it reaches the 50C or 60C that the Methyl cellulose needs in order to gel, the liquid will escape.
      Any ideas?

      Thanks for putting up this forum 🙂
      I would like to bake using a combination of sous vide and a conventional oven. Would it be possible to put the dough in a vacuum bag cook it sous vide at 37C for the dough to raise optimal and then put it in a conventional oven?

      Utilization of meat leftovers from sous-vide cooking
      Sometimes when you buy a nice cut of meat, your eyes are bigger than your and your beloved's stomach. So what to do with the leftovers?
      In Tyrolia (Austria) they make a "Gröstl", in Solothurn (Switzerland) they make a "Gnusch", in the Seftigenamt (a region in the Swiss canton Berne) they make a "Gmüder", and we (Pedro and SWAMBO) make a varying concoct using ideas from all of the three. We call it "Gröstl", but it is not necessarily a typical Tyrolean Gröstl, and it is different each time, and we usually do not top it with a fried egg as they do in Austria.

      All your meat leftovers
      Onion (compulsory)
      Any hard vegetable (we prefer celery stalks, or zucchini)
      Any salad (iceberg lettuce or endive/chicory or any other salad leaves, may contain carrot julienne)
      Fried potatoes, or alternatively sweetcorn kernels
      Sherry or wine or bouillon or the gravy you preserved from your last LTLT.cooked meat for simmering (I usually prefer Sherry)
      Eventually some cream (or crème fraîche)
      Salt, pepper, parsley, caraway seeds (typical for Tyrolean Gröstl), paprika, condiment (in Switzerland we use "Aromat" by Knorr, which contains sodium chloride, sodium glutamate, lactose, starch, yeast extract, vegetable fats, onions, spices, E552)'
      vegetable oil (I prefer olive oil)

      Mise en place

      cut your meat in small cubes or slices
      cut the onion(s) not too fine (place the first cut below your tongue to avoid tearing during cutting)
      cut the vegetables about 3-4 mm thick
      cut the salads to pieces smaller than 4 cm, distribute on the cutting board and season deliberately
      cut the potatoes to 1 cm cubes
      place 3 heavy skillets with ample oil on the stove


      in skillet 1, stir-fry the onions, add the hard vegetables still stir-frying, add salad, add sufficient liquid (Sherry or wine or bouillon or gravy) for simmering under a cover until soft. If desired, reduce heat and add some cream at the end.
      in skillet 2, stir-fry the potatoes until soft (in case of sweetcorn kernels, add to skillet 1 after stir-frying and use skillet 2 for skillet 3)
      in skillet 3, as soon as the vegetables and the potatoes are soft, sear the meat in just smoking oil for 30-60 seconds, then add to skillet 1

      You may mix the potatoes with the vegetables and meat to make a rather typical Gröstl, or serve the fried potatoes separately; we prefer the latter, as the potatoes stay more crunchy.
      Do not forget to serve a glass of good dry red wine!
