Adding rum to any fruit salad is a great idea! I used fruit that I happened to have - cantaloupe, little champagne grapes, apple, banana, some canned lychees, some blueberries. And I added some fresh lime juice with the rum - that added a nice little zip to it.
Scaled this recipe down to half- 3 servings for 2 people, really enjoyed the rum flavor, in addition to the various combination of fruits. Had great flavor, and made a great side dish to lunch. Made for Zaar tag.
