Orange/Blueberry Muffins

Orange/Blueberry Muffins (one of my very favorite muffin recipes ever!)

Sift together:
5 cups flour
1-1/2 cup sugar
2 tbsp. baking powder
2 tsp. soda
1 tsp. salt

Cut in 1 cup margarine to dry ingredients. Mix together in another bowl and add to dry ingredients:

1 cup orange juice concentrate
1 cup milk
4 beaten eggs
4 tsp. orange rind
Fold in 3 cups of blueberries.

Bake at 375F for 12 minutes, then bake at 325F for 12 more minutes. Cool slightly. While the muffins are still warm, dip tops in melted butter, then orange juice concentrate, and then into sugar. Let cool. Makes approximately 4-1/2 dozen. Can be frozen in a Ziplock freezer bag for up to a month.
