Cucumber soup is a type of soup made from cucumbers that have been blended until they become a smooth liquid and mixed with other ingredients like cream or broth. You usually start by cutting cucumbers into small pieces and adding them to a pot with some butter and sautéing them until they are softened. Then you add some liquid ingredients like chicken or vegetable broth, cream, and seasonings and let it all simmer together until the flavors combine. Once the soup is finished, you can garnish it with fresh herbs or a swirl of cream and serve it as is, or you can pour it into a blender to make it even smoother and creamier.
