1 C. plus 2 T. pastry flour (I used cake flour)
1 1/4 t. sugar
3 1/2 t. baking powder
2 1/4 t. kosher salt
12 1/2 T. cold butter cut in dice (1 1/2 sticks plus 1/2 T.)
3 C. all-purpose flour plus more for work surface
1 1/2 C. plus 2 T. buttermilk
1 large beaten egg
2 T. heavy cream
Preheat oven to 425 degrees F. and line baking sheet with parchment paper. Yield 8 or 9 large biscuits.
Place the pastry flour, sugar, baking powder, and salt in the bowl of a food processor and pulse until combined. Add the butter and pulse until the mixture appears as coarse meal. Dump mixture into a large bowl and add the all-purpose flour.
