1/2 tbsp baking powder
1/2 tsp sugar
1/2 tsp kosher salt
4 tbsp cold butter, cubed
6 tbsp buttermilk
1. Preheat oven to 400 degrees. In a bowl, whisk flour, baking powder, sugar and salt. Add the butter and, using your hands, rub the flour and butter between your fingers until the mixture looks like pea-sized crumbs.
2. Pour the buttermilk into the flour mixture. Using a fork, stir together until a loose dough forms. Press together to form a dough ball. Place on a floured surface and begin folding and kneading the dough to form many layers. I usually knead, fold dough onto itself, then turn, and repeat.
3. Roll dough until it's about 1/2-inch thick (if you want thicker biscuits roll until one-inch; they do rise when baking). Cut out biscuits with a 2-inch circle cutter. Place on a greased baking sheet and place in the fridge for 15 minutes. Bake for about 15-20 minutes or until slightly browned.
