These sourdough discard biscuits have tall, flaky layers, a crispy golden outside, and a soft, tender inside that pulls apart beautifully. A small amount of sourdough discard adds a subtle tang that makes them taste more interesting than a standard biscuit without being overpowering. They come together in about five minutes of active work, cost pennies per biscuit, and freeze beautifully — which means you can have fresh-baked biscuits on the table any morning of the week with almost no effort.

Instructions
In a mixing bowl add 2 cups of flour sifted, 1 tablespoon of baking powder, 1 teaspoon of sugar and 1 teaspoon of salt and combine.
Add the grated, frozen or cold, butter (½ cup) and fold into the flour mixture.
Pour ¾ cup milk and ½ cup sourdough discard into the bowl and fold into the dry ingredients until moist, do not over mix, it will still be a bit crumbly (but not dry).
Turn the dough out onto a lightly floured surface and shape into a flat rectangle.
Fold the right side of the dough just over the middle. Fold the left side over the right to the opposite edge of the dough, like folding a letter and gently press or roll into another rectangle. Turn the dough so the rectangle is horizontal, fold in the same way and repeat the folding process 2-3 times more.
Flatten the dough with hands or a rolling pin until it's an even thickness, approximately a ½ inch thick rectangle.
Cut the biscuits with a 2 or 2 ½-inch biscuit cutter. Flour the biscuit cutter before each cut and press down. Do not twist the cutter, just press down. Twisting will seal the edges and prevent rising
Layer the leftover cut dough, press or roll, then continue cutting rounds.
Place the biscuit rounds on a baking sheet lined with a baking mat or parchment. Place the biscuits in the freezer for 30 minutes before baking.
Preheat the oven to 425℉ (218℃). Place the tray from the freezer straight into the oven and bake for 15-20 minutes or until the biscuits are lightly browned.
Brush melted butter on the tops of the biscuits and serve hot.
