• Choose a method and combine flour, buttermilk powder, baking powder, sugar, salt, and baking soda until fully combined. Add shortening, cut into small cubes, and work into the dry ingredients until the mixture is the texture of coarse crumbs or very lightly dampened cornmeal.

To make one batch of biscuits

• Preheat oven to 450°F. Place on a large sheet pan lined with parchment paper.
• Combine 2 cups of biscuit mix and 7 tablespoons (½ cup minus 1 tablespoon) of milk. Mix to a cohesive dough. If dry, add 1 more tablespoon of milk. Place on floured counter and roll or press into a rectangle ½ inch thick. Use a biscuit cutter to cut out biscuits, pressing straight down, and pulling straight back up, without twisting the cutter.
• For drop biscuits, mix dough as directed and, using a medium scoop or ¼ cup measuring cup, portion out biscuits onto a lined sheet pan.
• Place biscuits on lined sheet pan, brush with melted butter and bake at 450° for 12 to 15 minutes, or until golden brown on top. Brush with more melted butter and enjoy.
