Ingredients

  • 335 grams all-purpose flour (2 2/3 cups)
  • 75 grams cake flour (3/4 cup)
  • 10 grams baking soda (2 teaspoons)
  • 4 grams baking powder (1 teaspoon)
  • 6 grams fine sea salt (2 teaspoons)
  • 15 grams granulated sugar (1 1/2 tablespoons)
  • 2 sticks salted, cultured butter, chilled and cubed (1 cup)
  • 1 1/2 cups buttermilk, chilled
  • 1 large egg
  • 1 tablespoon milk

Method

  • Heat oven to 425 degrees.
  • Line a baking sheet with parchment paper.
  • In a large bowl, whisk together flours, baking powder, baking soda, salt and sugar.
  • Using a pastry cutter or fork, quickly cut butter into flour mixture until it forms pea-size crumbs and is uniformly mixed.
  • (For flaky biscuits, you want the butter to remain cold.)
  • Make a well in center of mixture and pour in buttermilk.
  • Stir together until it just forms a moist, slightly tacky dough.
  • Turn dough out onto a lightly floured surface.
  • Knead 2 or 3 times, then pat out into a 3/4-inch-thick round.
  • Using a 2-inch round cutter, cut the biscuits.
  • Do not twist the cutter; doing so prevents proper rising.
  • To prevent sticking, dip the cutter lightly in flour between biscuits.
  • Also, do not reroll scraps, but pat them together and cut into rounds.
  • Transfer biscuits to baking sheet.
  • Whisk egg and milk together with a fork.
  • Generously brush egg wash on top of each biscuit.
  • Bake until brown, 15 minutes.
  • Serve hot.
