Special equipment: a popover or large muffin pan
Preheat the oven to 450 degrees F.
Place a popover or large muffin pan in the preheated oven for 10 minutes. In a mixing bowl, beat the eggs until they are foamy. Whisk in the milk. Add the flour, salt and pepper and beat just until the batter is smooth.
Pour the beef drippings in the cups of the hot pan, then pour in the batter filling the cups halfway and bake until the popovers are puffy and golden brown, about 30 minutes. Serve immediately.
