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

What each ingredient does

Butter
Enriches the onions and forms the fat base for the flour.
Whole-wheat flour
Cooked in the butter, it thickens the milk into a smooth soup.
Milk
Forms the liquid base that thickens as it heats.
Haricot beans
Add body and substance, making the soup heartier.
Sour cream
Adds richness and a slight tang at the end.

The step that matters

Heat gently, stirring continuously, until the soup thickens. Flour thickens milk only as it heats, and it can scorch or form lumps if left unstirred. Gentle, constant stirring keeps the soup smooth as it thickens and boils.

Flavor stand-ins for the parsley

Fit is the average pairing score against onion, butter, wheat, flour, milk, beans, 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).
