Peel and quarter the kiwis and carefully carve out the central white core. Slice each quarter into 3 long pieces to get curved, elegant slithers of fruit. Combine the mango cubes and kiwi slices in a serving bowl with the scooped-out flesh of the passion fruits.
Finely dice the preserved ginger and scatter it over the fruit salad. Drizzle with the ginger syrup, and squeeze over the lime juice. Toss the ingredients together carefully. Serve the fruit on its own or with ice cream or cream, and enjoy the sweet rewards of bliss.
