Chlodnik!

This cold beet soup is the perfect refreshment for a hot summer day. There are many versions, but here is an delicious representative from the excellent blog: Four Obsessions: Reading, Writing, Cooking and Crafting

3 C chilled buttermilk
1/2 C Sour Cream (optional, or substitute yogurt)
1 t salt
1 smallish garlic clove, finely pressed or minced
1 C chopped seedless cucumber (or take a regular cucumber and cut out the seeds before you dice it)
1/2 C chopped radishes
1/2 C chopped walnuts
2 T chopped fresh dill
ground black pepper
1 C diced beets ( freshly roasted or boiled beets; you could use canned ones or pickled ones if you prefer.)

Whisk together all ingredients except beets and chill. Top each serving of soup with beets. Really good!
