Fluffy Baking Powder Biscuits

1. In a large bowl, with a pastry blender, mix flour, baking powder, salt, and margarine or butter until dough resembles a crumbly mixture. 2. Slowly add the buttermilk until the dough is formed. Turn out onto a floured surface and knead for 50 seconds, or until it holds together. 3. Preheat oven to 400 degree Fahrenheit. Lightly butter a baking sheet. 4. Pinch off twelve small balls from the big dough. Roll each into a 1-inch golf ball size. Place 2 inches apart on greased pan and press down with the bottom rim of a glass to flatten. 5. Bake for 10 minutes or until golden brown. Cool on wire rack.
