Chanced upon this recipe on a barbeque web site. I use ground white pepper , rather tan the black pepper stated in the recipe. I use casserole-sized elbow macaroni. The original posted stated that he omite the optional food coloring. I also do not add food coloring. The following is what the original poster stated about the recipe.
"I got this recipe for Macaroni and Cheese from ‘Sylvia's Soul Food’ cookbook, however, I made two changes. Every time I make it, guests say it's the best they've ever tasted and ask for the recipe. I hope you like it."
