Martha likes to let the market guide her choices about which fruits to include. Choose a wide variety of textures, colors, and flavors for your salad. Try other combinations later in the year.
Make ginger syrup: In a heavy-bottomed saucepan over medium-high heat, combine sugar, ginger, and 1 cup water. Bring to a boil, and lower heat to medium. Cook for 20 minutes; set aside to cool.
In a medium bowl, mix together kiwis, orange, blackberries, plums, pineapple, nectarines, and coconut. Drizzle about 1 cup ginger syrup over the fruit mixture. Using a rubber spatula, gently stir the fruit.
Place heavy cream and confectioners' sugar in a large bowl. Using a wire whisk, whip cream to form soft peaks. Fold in amaretto.
Spoon 2 tablespoons whipped cream into each of six glasses, then some fruit; continue until the glasses are topped with 1/4 cup cream. Sprinkle with coconut, and serve immediately.
