One thing southern folks love is their buttermilk biscuits. My husband tells me this all the time! This homemade buttermilk biscuit recipe takes just ten minutes to mix, probably making it one of the easiest biscuit recipes you'll ever make! Don’t run out to the store tobuy buttermilk, just place a tablespoon of vinegar in a one-cup measuring cup and fill it with milk. Let the mixture stand for at least five minutes before using it to allow the milk to sour.
