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

What each ingredient does

Frijoles (beans)
Form the main body of the dish and absorb the flavours of the sauce as they cook.
Tomatoes
Provide acidity and liquid that break down during the long simmer into a thick sauce.
Bacon
Adds fat and smoky, savoury flavour, and browns on top in the oven.
Onions
Add sweetness and savoury depth as they soften during cooking.
Garlic
Adds pungent aroma that mellows and sweetens as it cooks.

The step that matters

Boil the beans in soda water, then wash off. Soaking and boiling beans in an alkaline solution softens the skins and shortens cooking time. Rinsing afterwards removes the soda, so the beans taste clean rather than bitter or soapy.

Swap the onion

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

  1. Okrafits better
  2. Capsicumfits better
  3. Spinachfits better
  4. Onionthe original

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