Water melon soup with grated citrus rind will surprise you in freshness and sparkling taste. And if you like you can provide it with a bite as well. But by all means use sweet, juicy water melons. It pairs excellently with lobster or crayfish meat. This soup is also an excellent way to consume fruit and it does not take a stove! Many non-fans of water melon, love this cold soup.

The art of making water melon soup

One of the most important things is to use fresh ingredients and a sweet water melon.  Make sure to properly remove the green skin and remove all seeds. The mellow sweetness can be easily off-set by using too dominantly tasting other ingredients. In this recipe we use the grated rind of both a lemon and orange, and a de-seeded Asian red chili provides some bite.

Along with the soup we offer crayfish tails or lobster meat as well as finely sliced rings of spring onions or chives. Also provide some crème fraiche to add to the soup to provide it with more creaminess and dampen the bite.

  1.  This soup also benefits from a bit longer maturing time, a half day or a day. But do this in the refrigerator and in a covered pot.
  2.  Preferably make the vegetable broth yourself as that will benefit the taste of this soup.
  3.  If you have no fresh crayfish or lobster meat, you can go for frozen or even canned material as substitute.
  4.  The recipe for preserved lemons you find here. If you do not have this available, use the rind of a half lemon.
