Moist-heat cooking refers to cooking methods that transfer heat through water, stock, another liquid or steam. These methods are used to cook delicate foods gently, hydrate ingredients, soften connective tissue and develop flavour in soups, braises and stews. The food may be immersed in liquid, partly submerged or exposed to steam.
Moist heat transfers energy to the food and can soften plant cell structures, gelatinize starch and convert collagen into gelatin during suitable long cooking processes. It can also leach water-soluble flavours and nutrients into the cooking liquid, which may be retained as part of the dish.
Moist-heat methods use liquid or steam as the primary cooking medium. Dry-heat methods use hot air, direct contact, radiation or hot fat. Combination methods such as braising use both.
At normal atmospheric pressure, boiling water is approximately 100°C at sea level. Pressure cookers can raise the boiling point of water and cook at higher temperatures. Moist-heat cooking therefore does not always remain below 100°C.
Chef’s tip: Choose the method according to the food’s structure and desired result. Gentle poaching suits delicate ingredients, while long braising is useful for collagen-rich cuts.
Key distinction: Moist-heat cooking uses liquid or steam to transfer heat; it does not mean every method is gentle or limited to 100°C.
