Orange Sugar: Place all ingredients in a blender and process until ingredients are completely mixed. Store in airtight container in refrigerator. Makes about 2 cups.
Muffins: Preheat oven to 350 degrees F. Grease and flour muffin tins. In a large bowl, cream together butter and 1 cup of Orange Sugar until smooth. Add eggs and beat until fluffy. In a separate bowl, sift together flour, Clabber Girl Baking Powder and soda. Add to creamed mixture along with buttermilk, beating until well blended. Stir in raisins and mandarin oranges.
Orange Honey Butter: Blend butter, honey and orange peel until smooth. Cover and refrigerate at least two hours.
While muffins are still warm, brush lightly with melted butter and sprinkle with Orange Sugar. Store in an airtight container. Makes about 1 1/2 dozen muffins. Spread Orange-Honey Butter on muffins, if desired.
Fill each muffin cup 2/3 full and bake at 350 degrees F for 15 to 18 minutes, testing with a toothpick for doneness.
