The Difference Between Sautéing and Sweating
Sautéing means quickly cooking ingredients in a small amount of fat over high heat, tossing them so the outside browns lightly and develops color. Sweating means cooking over lower heat so ingredients, especially onions, soften and release moisture without browning; it is often the first step in making soup and sauce bases.
Briefly covering onions while they sweat helps them soften faster in their own steam, but leaving the lid on too long prevents evaporation and can make them watery.
Overcrowding the pot makes it harder for steam to escape and produces a result closer to boiling than sautéing; cooking the ingredients in batches gives them better color.
The Difference Between Boiling and Simmering
Boiling is cooking at close to 100 °C / 212°F, when large bubbles continuously break across the water’s surface; it is used to boil pasta and eggs. Simmering is cooking at about 85–95 °C / 185–203°F, when small bubbles appear occasionally at the surface; most soups, sauces, and stews cook at this temperature.
Stew meat cooked in boiling water becomes tough because high heat contracts its proteins quickly. The same meat becomes tender and falls apart when simmered for hours. Patience is the ingredient a pot needs most.
Boiling water may seem fast, but it does not always give the best result; simmering is a patient method that softens ingredients’ fibers over time.
Deglazing the Pot
The browned bits (fond) left in the bottom of the pot after sautéing meat add valuable flavor and should not be discarded. Add a little liquid (wine, stock, or water) to the pot and scrape the bottom with a spoon to loosen the bits and create a rich sauce base; this process is called deglazing.
The pot should still be hot when you add liquid for deglazing; in a cooled pot, the browned bits harden and stick, making them difficult to scrape up.
Order Matters in Stews and Other Long-Cooked Dishes
For a stew, sear the meat first and remove it from the pot, then sweat the onion and garlic in the same pot. This order helps keep the meat from toughening too early and lets the vegetables pick up the fond from the bottom. Return the meat to the pot, add liquid, cover, and cook over low heat for a long time.
Red stew meat usually becomes fork-tender after simmering for 1.5–2.5 hours; for more reliable results, keep the heat low and wait rather than shortening the cooking time.
Choose the Right Pot Size
Using a pot that is too large for the ingredients makes liquid evaporate faster than necessary; a pot that is too small crowds the ingredients and keeps them from cooking evenly. Choose a pot large enough to hold the ingredients comfortably without leaving too much empty space.
