1 stick of cold unsalted butter
3/4 teaspoon kosher salt
2 teaspoons baking powder
1 cup of sourdough discard
Preheat the oven to 425°F with a rack in the upper third and grease or line a baking sheet with parchment paper.
Combine the flour, baking powder, and salt. Work the butter into the flour until the mixture is unevenly crumbly. Add the starter, mixing gently until the dough is cohesive.
Turn the dough out onto a lightly floured surface and gently pat it into a 6” round about 1” thick.
Cut biscuits out of the 6” round with a glass. Place the biscuits onto the baking sheet, leaving about 2" between them. Gently pat the left-over scraps into another round and cut more.
Bake the biscuits in the upper third of your oven for 20 to 23 minutes, until they're golden.
