Watercress and Cucumber Soup

A chilled, bright green soup that's ready in 15 minutes and is the ideal antidote to a hot summer day. Watercress blended with cucumber, yogurt, and a little lemon — it's vividly colored, peppery, and refreshing in a way that feels genuinely restorative.

  • ¾ tsp salt

Tips

  • The soup loses its vivid color after a few hours — make it close to serving time.

Ring the changes

  • Add a peeled avocado for extra creaminess and richness.
