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

What each ingredient does

Celery
Provides the main flavor and body of the soup once cooked and strained.
Soup stock
Adds savory depth to the broth the celery cooks into.
Cream or rich milk
Adds richness and a smooth, velvety texture to the finished soup.
Flour
Thickens the cream mixture so it blends smoothly into the soup.
Butter
Adds fat and flavor, and helps the flour thicken the cream mixture.

The step that matters

Mix in the flour and butter, then heat the cream mixture gently. Cooking the flour and butter briefly lets the starch thicken smoothly without lumps. Once the cream is added, keeping the soup below a boil prevents curdling and a grainy texture.

Swap the celery

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

  1. Nutmegfits better
  2. Jalapenofits better
  3. Capersfits better
  4. Celerythe original

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