1/2 cup milk
1/2 cup all-purpose flour
1/2 teaspoon salt
1.Let milk and egg stand at room temperature for 30 minutes. (Or you can do like I do and warm the milk in the microwave and run warm water over the egg for a few minutes.)
Combine all ingredients in a mixing bowl; beat just until smooth. Pour into four greased 6-oz. (or 8 2-oz.)custard cups; place on a baking sheet. Bake at 425 degrees F for 15 minutes. Reduce heat to 350 degrees F (do not open door). Bake 15-20 minutes longer or until popovers are deep golden brown (do not under bake). Serve warm.
