Fatback is as it sounds, the fat on the pigs back. It can be rendered for lard, or cubed and made into salt pork. I occasionally have a slab smoked along with the bacon and use it like bacon, but it's mostly fat. (When you're out of bacon, it's the next best thing!)BillHoo said:Yea, I think it's also known as "fatback". cooked with beans so that the lard may add flavor. Bacon has more flavor though.
