Topping: Mix together 1 cup of sugar and the juice of one orange (about 1/2 cup) and set aside for dipping the muffins before they are baked.
Muffins: Cream 1 cup sugar and butter. Add flour, soda, salt and sour cream. Stir until just mixed together. Fold in orange rind, raisins and nuts. (This is a stiff batter). Use a well-greased muffin tin. Bake at 350 degrees for 12 - 15 minutes. While muffins are warm, dip them in the sugar and orange topping. Cool on wire rack. Makes 12 muffins.
