Chef John s Popovers

1 tablespoon butter

cooking spray

2 large eggs

1 cup milk

1 cup all-purpose flour

½ teaspoon salt

1 pinch cayenne pepper

2 tablespoons shredded Cheddar cheese

Grease a 6-tin muffin pan with butter and cooking spray.

Whisk eggs, milk, flour, salt, and cayenne pepper together in a small bowl until smooth. Pour batter into each muffin tin, filling to about 3/4 of the way up the sides. Sprinkle about 1 teaspoon of grated Cheddar cheese atop each popover.

Place pan in a cold oven. Heat to 450 degrees F (230 degrees C) and bake until puffed and well-browned, about 30 minutes.
