3/4 cup plus 1 tablespoon cold buttermilk, plus more for brushing
Optional: turbinado sugar for topping
Instructions
Preheat the oven to 400°F.
In a medium bowl, whisk the flour, sugar, baking powder, baking soda, salt, and 1 teaspoon lemon zest. Cut the butter into 1/2-inch pieces and use a pastry cutter it into the flour mixture.
Add the 3/4 cup buttermilk to the flour and stir until all the buttermilk has just absorbed. Do not overstir. Use your hands to form the dough into a rough ball. Add the 1 tablespoon more buttermilk to help the dough come together.
Turn onto a lightly floured counter. Gently pat the dough out into a rectangle about 8” x 10” and about 3/4” thick (you may need to wash, dry and flour your hands to help pat it out).
Use a 3” biscuit cutter to cut the biscuits, pushing straight down (without turning the cutter) and transferring to a parchment lined baking sheet (you can also use a cookie cutter or use a knife to cut out a 3-inch circle). Ensure the edges of each biscuit are touching on the baking sheet to improve rise. You should get 6 biscuits out of the first cutting, then re-roll the dough scraps for final 2 biscuits.
Brush tops with buttermilk. Sprinkle with additional sugar or use turbinado sugar for a crunchy, glittery topping. Bake 15 to 17 minutes until lightly golden brown on top. Allow to cool for 10 minutes. Store leftovers frozen for up to 3 months or refrigerated for a few days (reheat in a 350 degree oven until warm).
