Bacon fat liquefies and becomes bacon drippings when it is heated. Once cool, it firms into lard if from uncured meat, or rendered bacon fat if from cured meat. Bacon fat is flavorful and is used for various cooking purposes. Traditionally, bacon grease is saved in British and southern U.S. cuisine, and used as a base for cooking and as an all-purpose flavoring, for everything from gravy to cornbread to salad dressing.
