Puree is a smooth, creamy mixture made by blending or pressing food to remove lumps and skins. It can be made from fruits, vegetables, or even meats and fish. The consistency of puree varies depending on the ingredient used - it could range from a thin liquid to a thick paste-like texture. Purees are often used as a base for sauces, soups, and desserts, adding richness and depth of flavor without chunks or fibers getting in the way.
