Chilled sorrel and lettuce soup

Gerla de Boer Lettuce soup

There is nothing more refreshing on a hot summer day than a chilled cup of soup. If you think of cold soups, Gazpacho and cucumber soup spring first to mind. Lettuce soup is not well-known, but I can assure you it is delicious!

When you have an allotment, you often have to battle with a glut of courgettes and salad. They all seem to be ready at the same time, and if you don’t want this to go to waste, you need to be thinking up recipes.

Chilled sorrel and lettuce soup

This chilled sorrel and lettuce soup is very versatile. You can serve this soup chilled or warm, as a base for green risotto, and even as a sauce for white fish such as cod or haddock.

Which lettuce to use?

Any type of lettuce is fine, but I would stay away from iceberg lettuce as it tastes watery. I have used a bright green salad and sorrel with a delicious lemony flavour. If you don’t have sorrel, then you can replace it with any salad. Try Rocket for a bit of a kick. If you grow Rocket yourself, you know it is much punchier than shop-bought. The reason is the sun, so if you want to have a milder rocket, you need to put it in a shadier area of your garden.

When I have guests over for a meal, I often include this sorrel and lettuce soup on my sharing board of appetisers.

Bon appetite!


p.s. Check out my creamy sorrel risotto. I use this soup as a base instead of stock.
