Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main earthy flavour and body of the soup.
- Buckwheat
- Thickens the soup and adds a nutty, grainy texture as it cooks.
- Onions
- Build a sweet, savoury base when sautéed in oil.
- Sour cream
- Adds richness and a tangy creaminess to the finished soup.
The step that matters
Adding the sour cream. Sour cream mixed with flour and added near the end, off the boil, helps it blend smoothly and resist curdling. Adding it to a rolling boil can cause it to separate.

Fit is the average pairing score against mushroom, buckwheat, onion, garlic, cream, vinegar, pepper. 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).
