Cool Melon Soup

This chilled melon soup is a sophisticated and refreshing vegetarian starter, perfect for warm summer evenings. By using fragrant, ripe Cavaillon or Charentais melons, the dish achieves a natural sweetness that is beautifully balanced by the savoury depth of white soy sauce and a hint of sherry vinegar. The addition of silken tofu provides a delicate, creamy contrast, making it a truly unique chilled dish that captures the essence of the season.

Ideal for elegant garden parties or a light lunch, this homemade soup feels refined yet remains simple to prepare. Using a cartouche of baking parchment ensures the melon softens evenly without losing its vibrant character. Served in chilled bowls with toasted Marcona almonds and almond oil, it offers a wonderful variety of textures and a nutty finish that will impress any guest searching for a light, healthy alternative to traditional gazpacho.

Ingredients for Cool Melon Soup

  • 110g (about 120ml ) silken tofu

  • 60ml white soy sauce

  • 2 very ripe 1.4kg melons (such as Cavaillon and Charentais)

  • Sea salt

  • Sherry vinegar

  • 1 medium white onion, halved, thinly sliced

  • 60ml lightly toasted Marcona almonds

  • 60ml almond oil, preferably extra-virgin cold-pressed

  • Fresh herbs, such as chervil sprigs or micro basil

  • White soy sauce, also known as white shoyu, is lighter in colour and flavour than standard soy sauce. It can be purchased at Asian markets and from amazon.com.

Meanwhile, cut rind from remaining 3 melon halves and cut flesh into 2" pieces. Melt butter in a large pot over medium-low heat. Add onion and cook, stirring frequently, until onion is translucent but not browned, about 10 minutes. Cut a parchment-paper round just large enough to cover surface of soup in pot.

Simmer, stirring occasionally, until melon is soft but not mushy and an instant-read thermometer inserted into melon reads 150°, about 15 minutes. Let cool slightly.
