Boil the potatoes in their skin until tender and the eggs until hard-boiled. Let both ingredients cool completely.
Peel them and, along with the cooked meat/cold cuts, dice them into small cubes (approx. 5 mm).
Originally, Okroshka was only poured over with kvass, but in modern kitchens, kefir mixed with water is often used to achieve the necessary sourness and thickness.
All ingredients must be diced into very small, uniform cubes, and the soup must be thoroughly chilled before serving.
Boil the potatoes in their skin until tender and the eggs until hard-boiled. Let both ingredients cool completely.
Peel them and, along with the cooked meat/cold cuts, dice them into small cubes (approx. 5 mm).
Wash the cucumbers and radishes and dice them into the same small cubes. Finely chop the green onion and dill.
Combine all the chopped solid ingredients (potatoes, eggs, cucumbers, radishes, cold cuts, onion, dill) in a large bowl. Season with salt and pepper.
In another bowl, mix the kefir (or kvass) with water and sour cream. Stir in the mustard and taste. If the mixture is not sour enough, you can add a drop of vinegar or lemon juice.
The base must be very cold. If using kvass, only add sour cream and mustard (kvass is already sour).
Let the solid mixture chill in the refrigerator for at least 1-2 hours if you didn't use already chilled ingredients.
The soup is often assembled only when serving: place the solid mixture at the bottom of the bowl and pour over the cold kefir/kvass base.
Serve immediately, extra cold, ideally with ice cubes.
