My grandmother has been making these easy buttermilk biscuits for as long as I can remember. They have 3 ingredients and are pretty much fool-proof. I make a double batch and freeze them either before or after cooking. Freezing them before cooking makes it easy to have fresh, hot biscuits for breakfast, but if you cook them first, you can make your own sausage biscuits for the freezer instead of buying them already prepared.
