![]() This is the recommended temperature since pasteurization occurs very quickly, however meat was very bland tasting, dry with a chewy consistency not found at lower temperatures. Weight of Chicken: before -84 grams after 64 grams weight loss =23.8% Texture and taste was similar to cooking at 140F.This may benefit further with short brine. Still retains sufficient moisture similar to that cooked at 140F. Weight of Chicken: before -84 grams after 74 grams weight loss =11.9 % This may benefit further with short brine. This is the temperature that Heston Blumenthal likes to cook his chicken. Weight of Chicken: before -82 grams after 74 grams weight loss =9.8 %Ĭhicken now has a pleasant soft white texture. Requires longer cooking times to ensure pasteurization.ġ40F is where myoglobin begins to change color, and shrinkage begins. Weight of Chicken before -84 grams after 77 grams weight loss = 8.4%Ĭomments: Had excellent flavor with some meaty texture not found at higher temperatures. Thus, the tip is to cook below this temperature to keep the meat tender for breast meat. NOTES: Collagen (fibrous protein constituting a good part of meat) contracts and gets tougher over 70☌/158☏. Source: Harold McGee - On Food and Cookingġ58☏ /70☌ - Breast meat in birds gets dry as collagen contracts and meat gets tougher.ġ65☏/ 73☌ - Leg meat is full of connective tissue and is chewy if cooked below this temperature. The fibers are still stiff and dry but meat seems more tender. At 160 ☏/ 70 ☌ connective tissue collagen begins to dissolve to gelatin. Meat served at this temperature med-rare is changing from juicy to dry. NOTES: At 140 ☏ changes are caused by the denaturing of collagen in the cells. Meat turns from pink to brown-grey color.ġ40☏/60☌ - Meat suddenly releases lots of juice, shrinks noticeably, and becomes chewy as a result of collagen denaturing.ġ60☏/70☌ - Connective tissue collagen begins to dissolve to gelatin. Red meat turns pink.ġ40☏/60☌ - Red myoglobin begins to denature into tan colored hemichrome. Coagulation produces large enough clumps to scatter light. Key Temperatures in Cooking Meat and Poultryġ20☏/50☌ - Meat develops a white opacity as heat sensitive myosin denatures. There is enhanced nutritional quality the sous vide technique preserves many nutritional qualities that other cooking methods tend to destroy There is little shrinkage and loss of juices Low and monitored temperatures can prevent meats from being overcooked Food can be seasoned and packed with small amounts of oil, butter or stock that would normally be required in large amounts when poaching foods. The technique is currently being used by many of our top chefs including: Thomas Keller, Paul Bocuse, Joël Robuchon, Charlie Trotter, Wylie Dufresne and Heston Blumenthal. In some cases food is cooked for 24 hours or more, although many excellent dishes can be prepared in under 30 minutes. It is a technique where the ingredients are put in a vacuum-sealed plastic pouch, usually for a long time and cooked at a low temperature (usually around 60☌ = 140☏).
