Meat juice reabsorption sous vide

Meat juice reabsorption sous vide - Crop person eating big appetizing hamburger with fried cutlet between fresh vegetables and green sauce at table with juice and French potatoes

I frequently cook sous vide at home--primarily for the sake of convenience. I have been generally satisfied with the results, and normally get tender and juicy meat.

One thing that bothers me, however, is the amount of liquid left in the bag when it's done. Even when adding nothing but, say, a steak, or a pork chop, patted dry, it is disheartening to see all the juiciness I could have had getting left behind.

A few weeks ago I saw notes from a class on khymos.org, where, in the context of a cook-chill-reheat scenario, Mr. Lersch relayed Bruno Goussalt's advice to cool in stages in order to maximize reabsorption. The reasoning seemed sound: "If plunged directly into ice water fat and gelatin can cause the juices to gel, thereby effectively preventing a readsorption of the liquid."

What I would like to know is how the same idea can be applied to the scenario in which the food is cooked and then eaten, without the chilling step. One idea I've toyed with is cooking to a target temperature (say, 155), then chilling to an acceptable serving temp (say, 130)

After reviewing a few sources, it looks like the key is getting the temp down to a spot where:

  1. It is hot enough for service
  2. Resorption is maximized

Looking a the graphs in this article on resting meat, it seems that after about 120°F (49°C), we get diminishing returns on the resorption, and it's still just hot enough. Down to 110°F (43°C), hardly any more liquid gets back into the meat, and it's starting to get a little cooler than I think I'd prefer.

In a sous vide situation, we can get the temp to right where we want in a faster and more controlled way that simply resting. The straightforward approach would be to drop it in a 120°F (49°C) water bath for a few minutes after cooking and before serving.

After forming my hypothesis, I took it to a non-scientific test with a chicken breast cooked to 155°F (68°C). I visibly noted the amount of liquid in the bag, then let it "rest" in a 120°F (49°C) water bath for about 10 minutes while preparing the vegetables. After all else was plated, I again inspected the amount of liquid in the bag and found it appeared to be noticeably less.

It's not clear to me how to evaluate the results in a more concrete rigorous way without the test itself interfering. So, all I can say is that there is at least anecdotal evidence in support of this technique.

Can I use juice from sous vide?

If you want to handle the sous vide juices as you would normal juices, you can just remove the proteins. Pour the juices into a pot then bring them to a simmer. The proteins should quickly coagulate at the top. Alternatively, you can microwave the juices for 1 to 2 minutes and they should coagulate.

How do you get rid of meat juice?

Does sous vide steak need to rest? Traditionally cooked steaks need to rest. That is, they need to be placed aside for five to ten minutes before cutting and serving. This resting period is to allow time for the temperature gradient within the steak to even out.

Should you let meat rest after sous vide?

Cooked meat should be allowed to \u201crest\u201d after cooking and before cutting. This permits the juices to be reabsorbed into the fibers of the meat. If you skip resting, you will lose more flavorful juices when the meat is cut.

Answer 2

I've seen the same thing, and mostly just take it as an excellent excuse to improve my game with respect to gravies, au jus, and reductions.

Answer 3

Is it possible that your sous vide cooking temps are too high to begin with? Most meat starts to lose a significant amount of moisture at about 60°C (140°F) (according to Modernist Cuisine, Heston Blumenthal, etc.) so keeping temperatures below this to begin with may help.

For example, I cook chicken breast at 58°C (136°F) for 2.5-3 hours which is sufficient to pasteurise them. While there usually is liquid in the bag, the meat isn't dry or unpleasant at all.
