In a large pot, combine the beef or pork ribs with water or broth. Bring to a boil, then reduce heat and simmer for 45 minutes to 1 hour, skimming off any foam.

Remove the meat from the pot, let it cool slightly, then cut into bite-sized pieces. Strain the broth and return it to the pot.
💡 Tip: Discard bones and excess fat. - 3
Add the rinsed sauerkraut and buckwheat groats to the broth. Bring to a simmer.
💡 Tip: Rinsing sauerkraut reduces its sourness if preferred. - 4
In a separate skillet, heat a little oil or use some rendered fat from the meat. Sauté the chopped onion and diced carrots until softened and lightly browned, about 8-10 minutes.

Add the sautéed vegetables, cubed potatoes, bay leaves, and allspice berries to the soup pot. Stir in the cooked meat.

Pour in the kvass. Bring the soup back to a gentle simmer and cook for another 30-45 minutes, or until the buckwheat and potatoes are tender.
⏱️ 45 minutes💡 Tip: Kvass adds a unique tanginess and depth; adjust the amount to your taste. - 7

💡 Tip: Taste and adjust seasoning carefully, as sauerkraut and kvass can be salty. - 8
Remove bay leaves and allspice berries before serving. Ladle the soup into bowls, garnish with fresh dill or parsley, and serve with a dollop of sour cream.
