Ambrosia is a traditional Southern fruit salad and an absolutely essential part of the Southern holiday meal. It is imperative that you use freshly grated coconut and the very best oranges. Sweeten sparingly and add just enough sherry to enhance, not overwhelm, the dish. A fine Ambrosia is far greater than the sum of its parts. Sadly, today you find many versions made with canned fruit cocktail, maraschino cherries and marshmallows. This recipe is the real deal.
