1/4 tsp. salt
2 tsp. finely grated orange peel or orange marmalade
2 large eggs

Beat in eggs, then buttermilk. Batter will look curdled. Stir in flour just until blended. Do not over mix. Add chocolate chips. Pour into muffin cups. Sprinkle muffins with topping (below).

Bake 16-18 minutes.

Makes 1 dozen muffins.
