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

What each ingredient does

Leftover beans
Form the main body of the dish, providing bulk and soft texture once warmed through.
Onions
Add sweetness and savour when fried lightly, softening and browning slightly in the pan.
Vinegar
Adds acidity that brightens the flavour of the beans and balances their richness.

The step that matters

Warm the beans over low heat. Beans are dense and scorch easily on the base of a pan. Low heat and regular stirring warm them evenly without sticking or burning.

Swap the beans

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

  1. Sesamefits better
  2. Black-eyed peafits better
  3. Soybeanfits about as well
  4. Beansthe original

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