Beef Suet is the hard fatty part of the cow that surrounds the kidneys and around the loins of the cow. Beef Suet has a white appearance, slightly crumbly, and almost dry to the touch.
You can render it down to produce tallow. Tallow is the rendered or melted-down version of suet. Tallow is simple to make at home DIY and gives you a clean, healthy animal fat that you can cook with, baste with, sauté, deep fry, or even spread like butter.
Also good for birds and is often used in raw pet food.
