Jeni's Popovers

2 eggs
1 cup unsifted flour (white)
1 cup milk
1/2 teaspoon salt
1 tablespoon melted butter

Preheat oven to 450. In mixing bowl, beat eggs slightly. Add remaining ingredients and beat just until smooth. (Do not over beat) Fill generously greased muffin cups or popover pans half full. Bake at 450 for 15 minutes, then reduce heat to 325 and bake 25 to 30 minutes or until golden brown. Prick crust with tip of knife during the last 5 minutes to allow steam to escape. Serve piping hot. 6-8 large popovers
