Paula Deen The Lady’s Cheesy Mac - 4 tablespoons butter, cut into pieces. 1/2 cup sour cream. 2 cups grated cheddar cheese. 3 eggs, beaten. 4 cups cooked elbow macaroni, drained. 1/2 teaspoon salt. 1 cup milk. Never thought of adding sour cream to macaroni & cheese, but I love sour cream... so it's worth a try!
