Heat oven to 425 degrees. Line baking sheet with parchment or a silicone baking mat, or use ungreased stoneware. In a large bowl, whisk together the flour, sugar, baking powder, pepper and salt. With a pastry blender or two knives, cut the butter into the flour mixture until you have coarse crumbs with some pea-sized pieces. Stir in milk just until soft dough forms. Do not overmix. Spoon onto baking sheet or stoneware (I use a large cookie scoop).
