5 egg whites
1 cup low-fat (2 percent) milk, at room temperature
1 cup all-purpose flour
2 T. corn oil margarine or butter, melted

Preheat the oven to 450°F. Grease a popover pan or 6 large custard cups, 31/2 inches in diameter, with corn oil margarine or butter, being careful to cover the entire inner surface. Lightly dust with all-purpose flour and place on a baking sheet. Combine all the ingredients in a blender and blend at medium speed for 15 seconds. Do not overmix. Divide the batter evenly in the prepared pan or among the custard cups and bake in the preheated oven for 20 minutes. Reduce the heat to 350°F. and bake for 25 more minutes. Pierce the side of each popover with a sharp knife and bake for 5 more minutes. Each Popover = 139 calories.
