Heat your oven to 425°F and grease or butter a cast-iron skillet or baking sheet.
-
Put the self-rising flour in a bowl and work in the cold butter and lard with your fingers or two forks until crumbly.
-
Stir in the buttermilk just until a soft dough comes together.
-
Turn onto a floured counter, fold the dough in thirds a couple of times for layers, and gently pat it out into an 8-inch round about 3/4-inch to 1-inch thick.
-
Cut straight down with a floured cutter without twisting, place them touching in the pan, and bake for 12 to 14 minutes until tall and golden brown.
