Summer Fest: Creamy Chilled Cucumber and Avocado Soup This soup tastes just as great the next day, so it’s definitely something that can be made ahead. I think this would be great served in shot glasses at a party. If you aren’t serving the soup with chopped tomatoes, I would add a tiny amount of sugar, honey, or agave nectar to the blender mixture (maybe 1/2 – 1 teaspoon) to help balance the flavors.
