# What You Need:
→ Dry Ingredients
01 - 2 cups all-purpose flour
02 - 1 tablespoon baking powder
03 - ½ teaspoon baking soda
04 - 1 teaspoon fine sea salt
05 - 1 tablespoon granulated sugar
→ Fats
06 - ½ cup unsalted butter, cold and cubed
→ Liquids
07 - ¾ cup cold buttermilk, plus extra for brushing
# How-To Steps:
01 - Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, baking powder, baking soda, salt, and sugar.
03 - Add cold cubed butter to the dry mixture. Using a pastry cutter or fingertips, work butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces.
04 - Make a well in the center and pour in cold buttermilk. Stir gently with a fork until just combined, avoiding overmixing.
05 - Turn the dough onto a lightly floured surface. Gently pat into a ½-inch (1.5 cm) thick rectangle. Fold the dough in half, then pat it out again. Repeat folding and patting two more times to develop flaky layers.
06 - Pat dough to a final thickness of 1 inch (2.5 cm). Cut out biscuits using a 2½-inch (6 cm) round cutter, pressing straight down without twisting. Gather scraps and repeat as needed.
07 - Place biscuits close together on the prepared baking sheet. Brush tops lightly with buttermilk.
08 - Bake for 13 to 15 minutes until tall and golden brown.
09 - Allow biscuits to cool briefly before serving warm.
