📝 About This Recipe

The quintessential Russian summer savior, Okroshka is a refreshing cold soup that balances the earthy, fermented tang of rye kvass with a crisp bouquet of garden-fresh vegetables. This traditional recipe features a sophisticated interplay of textures—crunchy radishes, creamy potatoes, and tender protein—all brought together by a zesty mustard-horseradish base. It is more than a meal; it is a cooling ritual that captures the very essence of Slavic culinary heritage.

🥗 Ingredients

The Foundation

  • 1.5 liters Rye Kvass (unfiltered, chilled, and not too sweet)
  • 200 grams Sour Cream (Smetana) (high fat content preferred for richness)

The Heart of the Soup

  • 3-4 medium Potatoes (waxy variety, boiled in skins and chilled)
  • 4 large Eggs (hard-boiled and chilled)
  • 300 grams Doctor's Sausage or Boiled Beef (diced into small cubes)
  • 3 small English Cucumbers (firm and seedless)
  • 6-8 pieces Radishes (peppery and crisp)

The Flavor Aromatics

  • 1 large bunch Fresh Dill (finely chopped)
  • 1 bunch Green Onions (finely sliced)
  • 1-2 teaspoons Russian Mustard (spicy variety)
  • 1 teaspoon Prepared Horseradish (white, non-creamy type)
  • to taste Salt and Black Pepper (sea salt preferred)

👨‍🍳 Instructions

  1. 1

    Begin by boiling the potatoes in their skins (in salted water) until tender, approximately 20-25 minutes. At the same time, hard-boil the eggs for 9-10 minutes.

  2. 2

    Drain the potatoes and eggs immediately and plunge them into an ice bath. This prevents overcooking and makes peeling much easier.

  3. 3

    Once completely cold, peel the potatoes and the eggs. Dice the potatoes into uniform 1/2-centimeter cubes to ensure a consistent texture.

  4. 4

    Separate the egg yolks from the whites. Finely dice the egg whites and set aside. Place the yolks into a small mixing bowl.

  5. 5

    Create the flavor paste: Mash the egg yolks with the Russian mustard, horseradish, and a pinch of salt. Stir in a few tablespoons of kvass to create a smooth, pourable slurry.

  6. 6

    Finely chop the green onions. Place them in a large mixing bowl, sprinkle with a generous pinch of salt, and bruise them lightly with a wooden spoon until they release their juices.

  7. 7

    Dice the cucumbers and radishes into small, even pieces. If the cucumber skin is tough, peel it partially to create a striped pattern.

  8. 8

    Dice your choice of protein (sausage or beef) into cubes matching the size of the potatoes.

  9. 9

    Combine the diced potatoes, egg whites, protein, cucumbers, radishes, and chopped dill in the bowl with the bruised green onions.

  10. 10

    Pour the egg yolk and mustard slurry over the dry ingredients and toss gently to coat everything in the flavor base.

  11. 11

    Slowly pour the chilled rye kvass over the mixture. Stir gently to combine without bruising the delicate vegetables.

  12. 12

    Taste the soup. Depending on the sweetness of your kvass, you may need more salt or a touch more mustard for balance.

  13. 13

    Chill the assembled soup in the refrigerator for at least 30 minutes before serving. This allows the flavors to meld and the soup to become ice-cold.

  14. 14

    Ladle the thick soup into chilled bowls, ensuring a generous amount of the solid 'salad' in every serving.

  15. 15

    Finish each bowl with a dollop of cold sour cream and an extra sprinkle of fresh dill.

💡 Chef's Tips

Always use 'bread kvass' (temny or khlebny) rather than fruit-flavored versions for an authentic savory profile. If you cannot find kvass, a 50/50 mix of sparkling water and kefir with a squeeze of lemon makes a decent substitute. Bruising the green onions with salt is the 'secret' step that infuses the entire broth with a deep, aromatic onion flavor. Ensure all ingredients are diced to a similar size; the elegance of Okroshka lies in its uniform, confetti-like appearance. Wait to add the kvass until just before serving if you prefer the vegetables to remain maximumly crunchy.

🍽️ Serving Suggestions

Serve with a thick slice of toasted dark rye bread rubbed with a raw garlic clove. A side of cold, salt-cured pork fat (Salo) provides a rich contrast to the acidic soup. Pair with a glass of chilled vodka or additional cold kvass on the side. For an extra kick, serve with a small side dish of extra horseradish and spicy mustard. This dish is best enjoyed outdoors on a hot afternoon as a light lunch.
