Preheat oven to 425°F (220°C). Preheat a 12-cup muffin tin in the oven.

Whisk flour, milk, eggs, and salt in a bowl until smooth.

Remove the muffin tin. Add oil or beef drippings to each cup (~1/4 inch deep). Return to oven for 5 minutes until sizzling.

Pour batter into the hot muffin cups, filling half.

Bake 20-25 minutes until golden brown, ensuring the oven door remains closed.

Serve immediately.
