Make homemade buttermilk biscuits by combining 2 cups of flour, 4 teaspoons of baking powder, 1/4 teaspoon of baking soda and 3/4 teaspoon of salt. Add 2 tablespoons of butter and 2 tablespoons of shortening into the mixture until it's crumbly, and add 1 cup of chilled buttermilk. Stir only until the ingredients are combined, and then fold the dough on a floured surface before cutting out 1-inch thick biscuits. Bake the biscuits at 450 degrees Fahrenheit for 20 minutes.
Another recipe for buttermilk biscuits calls for buttermilk or whole milk combined with lemon juice. Cut 1/2 cup of cold butter into 2 1/4 cups of self-rising soft-wheat flour, and chill the crumbly mixture for 10 minutes before adding in the 1 1/4 cups of buttermilk. After the ingredients are just combined, briefly knead the dough on a floured surface, and fold the dough over itself several times. Cut out 1/2-inch thick biscuits with a 2-inch cutter, and bake them at 450 degrees for 13 to 15 minutes. Brush the tops of the cooked biscuits with melted butter serving.
One recipe suggests brushing the biscuits with buttermilk prior to cooking for a browned surface. Add cheese or bacon for a variation on the original recipe.
