Buttermilk Biscuits

I made these the other day and they were delish!!

2 cups self-rising flour
2 tablespoons sugar
1 teaspoon baking powder
1 1/2 cups buttermilk or sour milk, divided
1/2 teaspoon salt
3 Tablespoons salted butter
3 Tablespoons shortening

Preheat oven to 400 degrees Fahrenheit. Grease four 9 x 13 pans with butter. In large mixing bowl, combine all dry ingredients. Next, cut in butter and shortening until pea-sized. Now, add 1 cup of the buttermilk or sour milk. If it looks too dry, you can add a little bit more. Gently knead for about one minute. Pat out onto a floured surface and cut out 24 biscuits with a floured glass or biscuit cutter. Place each biscuit on the greased pans. Now, brush tops with reserved buttermilk or sour milk. Bake until brown around the bottom edges, approximately 20 minutes. Serve hot with your favorite toppings!
