Preparation:
1. In a small bowl mix together yeast, sugar, and water; let proof 10 to 15 minutes. In food processor fitted with steel blade, combine 2 cups flour, baking powder, and salt. With on/off pulsing, cut in butter. With motor off, quickly add yeast mixture and buttermilk; process until dough pulls away from sides of bowl. Add more flour if dough is sticky.
