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

What each ingredient does

Onions
Form the main body of the dish, becoming sweet and soft as they cook.
All-purpose flour
Coats the onion rings so they brown and crisp when fried.

The step that matters

Fry the onion rings for 5 to 6 minutes until golden. Frying at the right heat until golden gives a crisp coating and cooked onion inside. Too little heat leaves them greasy, while too much browns the coating before the onion softens.

Swap the onion

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

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

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