Beef fat, also known as tallow, is the rendered fat obtained from beef. It is a versatile cooking ingredient that can be used for frying, sautéing, and roasting. Beef fat has a high smoke point and a neutral flavor, making it ideal for high-heat cooking methods like deep-frying. It can also be used as a flavorful substitute for butter or oil in many recipes, adding richness and depth to dishes like roasted vegetables, mashed potatoes, or pie crusts.
