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

What each ingredient does

Yam
Forms the bulk of the dish and becomes tender as it simmers in the sauce.
Tomato paste
Provides concentrated tomato flavour, colour and body to the sauce.
Onions
Softened by sautéing, they add sweetness and savoury depth to the base.

The step that matters

Simmering the yams. Yams need enough liquid and gentle heat to cook through evenly. Too little water can scorch the tomato paste on the bottom of the pot, so adding water as needed keeps the sauce loose and the yams cooking evenly.

Swap the yam

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

  1. Capsicumfits better
  2. Okrafits better
  3. Potatofits better
  4. Yamthe original

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