In a 1- to 1 1/2-quart pan, combine 1 1/2 cups water, 1 cup sugar, 10 slices unpeeled fresh ginger (each about the size of a quarter), and 5 slices (1/4-in. thick) lime. Simmer until liquid is infused with ginger flavor, about 7 minutes. Remove from heat. Stir in 2 tablespoons fresh lime juice; strain and cool. On a platter, arrange 3 quarts sliced or chopped fruit. Choose from mangoes, yellow watermelon, cantaloupe, honeydew melon, nectarines, golden raspberries, yellow and green kiwi fruit, green grapes, and golden plums. Pour syrup into a bowl or glass; garnish with 3 lime slices. Serve with fruit.
