Ingredients
 1 1/2 cup(s) all-purpose flour  
 1 1/2 tsp baking powder  
 1/2 tsp baking soda  
 1/4 tsp table salt  
 1/4 cup(s) butter, cold  
 1/2 cup(s) buttermilk, cold  
 1 Tbsp all-purpose flour, for rolling out dough  
Instructions

    * Preheat oven to 450ºF.

    * In a medium bowl, combine flour, baking powder, baking soda and salt; mix well.

    * Cut cold butter into about 8 pieces. Work butter into flour mixture with a pastry cutter, knife or fork until butter forms pieces the size of small peas. (Do not blend butter in completely; dough should look lumpy.)

    * Make a well in center of dough and pour in buttermilk. Work buttermilk into dough just enough to moisten all of flour: start with a pastry cutter and finish by kneading dough against side of bowl about 4 to 6 times until all flour has been worked in and dough comes together. Do not overwork; small pieces of butter should still be visible.

    * Working on a lightly floured surface, roll out dough into a 6- X 8-inch rectangle, about 1/2-inch thick. Cut dough into 12 equal pieces with a sharp knife. Place biscuits on an ungreased cookie sheet and bake until tops start to turn golden, about 10 to 12 minutes. Yields 1 biscuit per serving.

Notes

    * Hint: The less you work the dough, the better the biscuits will be.
