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

What each ingredient does

Onions
Break down into sweetness and develop browning as their sugars caramelize.
Butter
Adds fat for frying and a rich, nutty flavor as it browns.
Lard or drippings
Adds fat that conducts heat well and carries savory flavor for frying.

The step that matters

Remove the cover and continue to cook until browned. Covering first traps steam and softens the onions, but browning needs dry, direct heat. Leaving the lid on too long makes them stew rather than brown, so uncover once they are partly soft and keep cooking until golden.

Swap the onion

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

  1. Capsicumfits better
  2. Potatofits better
  3. Carrotfits about as well
  4. Onionthe original

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