Why it works: Cranberry and onion match in chemistry and in kitchens. They rank in the top 12% of all ingredient pairs, and 166 recipes mention both. Both carry ethyl butyrate, which smells apple, fruity. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the beans
Wash beans and soak overnight.
Cook the soup
Cook beans with kolbasz in a soup kettle along with onion, salt, and peppercorns to taste.
Make roux: brown roux ingredients until brown in color.
Add 1 cup water to roux and bring to a boil.
Add roux to soup and cook about 5 minutes until soup comes back to a boil.
Finish with sour cream
Take 1/2 pint sour cream at room temperature.
Mix in 1 tablespoon flour to thicken.
Add hot soup to sour cream 1 tablespoon at a time, mixing well until the cream thins, then add to hot soup to prevent curdling.
Bring soup back to a gentle boil, then turn heat off.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried cranberry beans
- Form the body of the soup as they soften and release starch during cooking.
- Kolbasz
- Adds smoky, savory flavor and fat to the broth as it cooks.
- Sour cream
- Adds tang and creamy richness to the finished soup.
- Flour
- Thickens the soup as a roux, giving it a smoother body.
The step that matters
Tempering the sour cream. Sour cream is acidic and can curdle when added directly to very hot liquid. Thinning it gradually with hot soup first raises its temperature and loosens it, so it blends in smoothly instead of separating.

Fit is the average pairing score against cranberry, beans, flour, cream. 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).
