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

What each ingredient does

Bran
Thickens the broth as it simmers, giving the soup its body and texture.

The step that matters

Simmering until reduced by half. Reducing the liquid concentrates the flavor and thickens the soup. Stopping too early leaves it thin and watery, while boiling too hard can scorch the bran on the bottom of the pot.

Swap the onion

How well each one fits the dish's main ingredients (pepper, molasses):

  1. Capsicumfits better
  2. Mustardfits better
  3. Carrotfits better
  4. Onionthe original

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