Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sour cream
Adds richness and a creamy body, and softens the sharpness of the kwass.
Kwass
Provides the tangy, slightly sour fermented base that gives the soup its character.
Beet greens
Add earthy flavour and colour, and bulk to the soup once finely chopped.
Cucumbers
Contribute crisp texture and fresh, cool flavour.
Crayfish tails
Add delicate, sweet seafood flavour and tender texture.
Sturgeon
Adds rich, meaty texture and a savoury flavour.

The step that matters

Incorporate the sour cream into the soup mixture. Sour cream can curdle or separate if it is added to very acidic or warm liquid. Whisking it in gradually with cold liquid keeps the soup smooth and creamy.

Flavor stand-ins for the cucumber

Fit is the average pairing score against tarragon, chervil, chive, fennel, shallot, crayfish, sturgeon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
