About Bacon grease
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.
Bacon, or bacon fat, is often used for barding roast fowl and game birds, especially those that have little fat themselves. Barding consists of laying strips of bacon or other fats over a roast; a variation is the traditional method of preparing filet mignon of beef, which is wrapped in strips of bacon before cooking. The bacon itself may afterwards be discarded or served to eat, like cracklings.
One teaspoon (4 g, 0.14 oz) of bacon grease has 38 Calories (160 kJ). It is composed almost completely of fat, with very little additional nutritional value. Bacon fat is roughly 40% saturated. Despite the health consequences of excessive bacon grease consumption, it remains popular in the cuisine of the American South.
