Instructions:
Preheat oven to 400°F.
Sift the flour into a bowl. Work in the butter (or other fat) until crumbly.
Add milk (sweet milk or buttermilk) and sugar (if using). Stir until combined into a wet, sticky dough.
Lightly flour your surface and turn out the dough. Toss it gently in flour to prevent sticking.
Flatten the dough into a square and fold in the edges to form layers. Repeat the folding process.
Cut the dough into rounds or squares without twisting the cutter.
Place the biscuits in a hot, lightly oiled cast iron skillet, making sure they touch each other slightly.
Bake for about 20 minutes, or until golden brown.
Enjoy your warm, fluffy biscuits! They should be perfect with butter, honey, or jam.
