In my family, ambrosia is usually made with oranges, coconut, and sugar. My friend Betty Maxwell used to make this for my daddy all the time. He loved ambrosia. You don’t have to wait until oranges are in the peak season to enjoy this—just use a lot more sugar for sweetness.
Pour the orange juice into a medium bowl. Peel and core the apples, then grate them into the orange juice using the large-hole side of the grater. Add the pineapple, sugar, and coconut. Mix well, adding more orange juice if the mixture is not juicy enough. The apples will continue to absorb juice, and orange juice can be added as needed to keep it as juicy as you like. Store in the refrigerator until ready to serve.
Choose a sweet apple that you like. My favorite is Golden Delicious.
