Before You Start
1. Preheat the oven to 375°F on Bake Mode with a rack set on position 3.
2. Sift together dry ingredients.
3. Cut the butter into eight pieces and add with the shortening to the dry ingredients.
4. Rub the butter and shortening into the flour between your hands until it looks like coarse cornmeal.
5. Add in the buttermilk and gently mix together with a spatula or your hands until it forms a dough.
6. Turn it out onto a lightly flour-dusted counter and fold it a couple of times to smooth out the dough.
7. Press down into a circle, ¾-inches thick. Cut out biscuits with a 3-inch cutter — gently press together the extra dough and cut out as many as you can. Try not to overwork the dough or the biscuits will become tough when baked.
8. Place on parchment-lined baking pan and brush the tops with buttermilk.
9. Bake until golden brown, about 24 minutes.
