Basic Muffins

Lightly grease ten or twelve 2 1/2-inch muffin cups or line with paper baking cups; set aside.

In a medium mixing bowl stir together flour, sugar, baking powder, and salt. Make a well in the center. In a small mixing bowl combine egg, milk, and oil; add all at once to flour mixture. Stir just till moistened. (The batter should be lumpy.) Stir in fruit and/or lemon peel, if desired.

Fill prepared muffin cups two-thirds full. Bake in a preheated 400 degrees F oven about 20 minutes, or till golden. Remove from pans; cool slightly on racks.
