There are so many variations on Buttermilk Biscuits that it's not even funny. Want to make the very best? Then follow my recipe :-)
2 cups flour
1 t sugar
1 T baking powder
3/4 t baking soda
3/4 t salt
8 T (1 stick) butter, softened to room temperature
3/4 c buttermilk
Preheat oven to 400. In a large bowl or food processor, combine flour through salt. Cut in the butter with your fingers or processor until mixture looks like crumbs. Make a well in the center and pour in the buttermilk, stirring just until it comes together. Pour out onto a piece of parchment paper and knead a few times. Fold dough over on itself 4 to 5 times and form into a rectangle. Cut into 12 pieces and round corners gently with hands. Place each biscuit into a sprayed muffin cup. You can bake them on the parchment paper, but they may fall over. Bake for 12 to 15 minutes, until light gold on top.
Note - can also be cut into rounds or dropped by spoonfuls if desired.
