These bulk packages are raw unadulterated pork fat. Leaf fat is derived from around the kidneys and the loin area. It is said to be the purest softest fat on the animal making it ideal for rendering into lard and used for baking or other uses, like candles. Our pork fat is often used by home chefs to add to sausage when a higher fat content is needed. We've also been told that once rendered our pork fat makes the best lard for pie crusts!
