Recipes are like music. Each ingredient adds its own notes to the melody of the final product. Musical pieces that take a single melody and present it in different ways are often called "variations on a theme." "Variations on a Theme: Whole Grain Muffins" is a cookbook that presents a basic muffin recipe followed by 60 variations. The recipes are grouped into four categories: Relatively Normal, A Little Odd, Filled, and Layered. With recipes that range from Cinnamon Raisin to Gingerbread to Banana Split to Strawberry Cheesecake, you are sure to find a muffin you will love
