Almost any variety of green-fleshed melon, such as Galia or Honeydew, can be used for this very pretty soup, but it is essential that the melon be perfectly ripe and sweet. Serve the soup as a refreshing first course when the weather is hot, dressing up each bowlful with a swirl of berry purée and some whole berries.
Try orange-fleshed melon, such as Ogen, Charentais or Cantaloupe, and top the soup with sliced kiwi fruit instead of the red berries. * Use 2 kg (4½ lb) watermelon instead of the green melon. Chop the flesh, discarding the seeds, then purée with the lime juice and 1 seeded and chopped fresh green chilli instead of the ginger. Coarsely crush the blueberries with the raspberries and/or strawberries, adding 1–2 tbsp orange juice. Omit the yogurt.
All melons provide vitamins B and C, and are very low in calories.
