Adapted from Alton Brown. These can also be made in muffin tins for personalized servings.
Ingredients
2¼ cup all-purpose flour
1½ teaspoons kosher salt
4 large eggs, at room temperature
2 cups whole milk, at room temperature
¼ cup beef drippings (or melted butter, or vegetable oil. Use as much of the drippings as you can first then supplement with other options to get a full ¼ cup.)
Instructions
Preheat oven to 400F. Put 2 tablespoons of the beef drippings into a 9"x13" baking dish, then warm it in the oven while it preheats.
Mix the flour and salt in a large bowl, then carefully stir in the remaining ingredients.
Use a hand blender or food processor to blend and smooth the mixture, removing all lumps.
Pour the mixture into the warm baking dish.
Bake for 35 minutes or until golden.
