The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Peanuts (in the method)
Form the body of the soup and give it its main nutty flavour.
Butter
Adds richness and fat, carrying flavour through the soup.
Flour
Thickens the soup when cooked with the melted butter.
Milk
Adds creaminess and smoothness to the soup.

The step that matters

Stirring in the butter and flour mixture. Cooking flour in fat before adding it helps prevent lumps and gives a smooth, evenly thickened soup. Stirring steadily as it goes in keeps it from clumping.

Swap the celery

How well each one fits the dish's main ingredients (milk, butter, onion, flour):

  1. Cinnamonfits better
  2. Capersfits better
  3. Garlicfits better
  4. Celerythe original

Fit is the average pairing score against milk, butter, onion, flour. Candidates are from the same food group and used in at least 100 recipes.
