Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cannellini beans
- Blended into a purée that gives the soup its body and thick, creamy texture.
- Chicken broth
- Forms the liquid base that carries the bean purée and cooks the soup.
- Egg yolks
- Enrich the soup and thicken it gently when heated without boiling.
- Milk
- Adds moisture and softness, mellowing the richness of the yolks.
- Parmigiano reggiano cheese
- Adds savory, salty depth and a rich, nutty flavor.
The step that matters
Cook until hot, but not boiling. Egg yolks thicken as they heat, but boiling can scramble them into curds and make the soup grainy. Keep the heat gentle once the yolk mixture is added.

Fit is the average pairing score against beans, chicken, milk, egg, cheese, 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).
