Prepare the dough ahead of time. Cut lard into the flour until it is in small pieces. Stir in the starter, sweetener, and milk until a soft dough just comes together. Cover and place in a warm spot for 7-12 hours.
Preheat oven to 400°F. Combine salt, baking powder, baking soda, black pepper, and garlic powder in a very small bowl until evenly mixed. Sprinkle dry mixture over fermented dough, add cheese, and knead until it comes together into a cohesive, soft mass.
Roll the dough out to ½-inch thick. Cut with 2- to 3-inch biscuit cutter and place the biscuits in a 10-inch oven-proof skillet, one next to another.
Bake 20-30 minutes, or until golden brown on the top and bottom. Serve hot with butter or drippings.
