From Lyn Rosetto Kasper and Sally Swift's book, The Splendid Table: How to Eat Supper , this recipe originated in Gainesville, Florida, and pays homage to the late Mamo Lo Alexander and her soul food restaurant, where she was a local folk hero. They write, Her broccoli casserole magically transformed the dour stalks of green into something rich, sweet and satisfying by combining them with a luxurious and ultra-soulful melange of eggs, cheese, sugar and cushiony white bread. We make a batch to split (with a tiny bit left over for the next day) whenever we are in desperate need of culinary comfort, southern-style.
