Combine the sugar, 1/4 cup water, ginger and lime
zest in a small saucepan
. Bring to a boil and cook until the sugar
is melted. Remove it from the heat and refrigerate until cold.
Strain the mixtures into a large bowl and toss in the strawberries, kiwis, mango, oranges, pineapple and papaya to coat. Cover and refrigerate again until cold, at least 1 hour.
Serve in small bowls and garnish with the chopped mint.
