Preheat over to 375°F, prepare pans. Combine dry ingredients & blend well. Melt butter, remove from heat & stir in juice, eggs & rind. Add dry mix to wet mix until just combined. Spoon into pans & bake for 15-20 mins or until nicely browned. Remove from pan while warm & dip in topping. Variation: A cup of raisins added to this batter makes this a delicious muffin for any time of day.

Topping: Combine melted butter & juice, measure sugar into separate dish. Dip top of muffins into butter then sugar.
