In a small saucepan on high heat, combine the lime juice, water, pineapple juice, and honey. Bring the mixture to a boil. After three minutes, remove and cool down. Add lime zest and ginger and stir. May be done a day ahead and stored in the refrigerator.
In a large bowl, add pineapple, mango, mandarins, and grapes. Can be done a day ahead. Cover and refrigerate. Do not pre-prep kiwi if making ahead of time.
When ready to serve or an hour before, cut and add kiwi and half of the raspberries. Add enough dressing to coat the fruit. Gently stir without breaking apart raspberries and top with remaining raspberries for a finished look. Serve.
Notes
Toasted coconut adds even more tropical flair to the salad.
