Pressure cooking refers to the process of cooking food at high pressure and temperature. Antonyms for pressure cooking could be slow cooking or low-temperature cooking, where food is cooked slowly at a lower temperature. Another antonym could be uncooked or raw food, which has not been subjected to any cooking method. Other antonyms could be baking, roasting, grilling, or frying, which involve different cooking methods, tools, and temperatures. Each of these methods can produce different flavors, textures, and results. While pressure cooking is a fast and efficient method, it is not always the best option for all types of food or dishes. Choosing the right cooking method requires consideration of the ingredients, recipe, and personal taste preferences.
