I'm so enamored with 
mammee apples. They aren't found commonly here, but I sometimes find them at Maku'u farmer's market from vendors/growers who embrace exotic fruits. Firm and tangy, they ease my craving for a summer nectarine or apricot.

3 cups chopped ripe mammee apple

1/2 cup vinegar (used homemade pineapple vinegar, if using something strong, may want to use less.)
1 tablespoon curry powder
1/3 cup diced shallots
2 in piece grated fresh ginger
Mix all ingredients together in medium sauce pan.
