Boiling slowly is a cooking technique used to cook food gently and slowly. Simmering, which is done by boiling slowly at a low temperature, is a common way to cook soups, stews, and sauces. Stewing is another way to boil slowly, but it involves cooking food in liquid for a longer period of time. Seething is a similar technique to simmering, but it is done at a higher temperature. All of these techniques involve boiling slowly, which helps to bring out the flavor of the food while also ensuring that it is cooked thoroughly.
