How can you tell the difference between back fat and leaf lard? It is really quite simple it's all about texture. Unlike back fat that is a smooth, consistent piece of fat, leaf lard has a brittle texture and you can break it into small pieces with your fingers. It is firmer than back fat at room temperature because it found inside the animal's body not on the outside.
