Ingredients
Method
- Prepare the core ingredients: Boil the potatoes and eggs ahead of time, then drain and run under cold water to cool completely. Once cool, peel and dice them into small, uniform pieces.
- Chop fresh ingredients: Finely dice the cucumber and radishes. Finely chop the scallions and fresh dill. If using sausage, dice it to a similar size as the other ingredients.
- Combine the solids: In a large serving bowl or pot, combine the diced potatoes, eggs, cucumber, radishes, scallions, dill, and sausage (if using). Gently stir to combine all the ingredients.
- Mix the liquid base: In a separate pitcher or bowl, whisk together the chilled kefir and chilled sparkling water. Add salt and pepper to taste. If you like, you can also whisk in a teaspoon of Dijon mustard or horseradish for extra flavor.
- Assemble and serve: Divide the solid ingredient mixture evenly among individual serving bowls. Pour the kefir-water mixture over the solids.
- Chill: The soup is best served very cold. You can add a few ice cubes to the bowl just before serving or refrigerate the mixed soup for at least an hour to let the flavors meld.
- Garnish: Serve with a dollop of sour cream and a sprinkle of extra fresh dill on top.
Notes
Classic Kvass base: For a traditional version, substitute the kefir and mineral water with chilled, unsweetened rye kvass.
Vegetarian: Omit the ham for a delicious vegetarian option.
Different liquids: Buttermilk, plain yogurt thinned with water, or even salted Ayran can be used in place of kefir.
