1 Preheat oven to 350°F(175°C). Combine the flour, baking powder, baking soda, sugar, and salt in the bowl of a food processor outfitted with a plastic blade. Pulse until well-blended. Add the butter and pulse until mixture resembles coarse meal, about 5 seconds.

2 Transfer mixture to a bowl and add the buttermilk.

3 Stir with a fork until it forms a dough.

4 Drop spoonfuls of the mixture onto a greased baking sheet, 1-inch apart from each other. The dough may also be spooned on top of savory fillings to form a crust. Bake until golden-brown, about 25 minutes.
