Bacon drippings also makes great gravy. Mama and my grandmother used bacon a lot. Grandpa made his own special sausage and my grandmother could make some dark, strong gravy. Mama made these little biscuits with lard and buttermilk. Crispy outside and flaky in the middle. I get real close to mama’s gravy, but her biscuits I can’t touch. You can use cornmeal. Originally ‘sawmill gravy’ used cornmeal. During the depression folks made gravy with lard and water. No milk, no meat,you use what you have.
