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

What each ingredient does

Young white onions
Form the main body of the dish, becoming soft and tender as they simmer.
Sweet cream
Adds richness and a smooth, velvety texture to the cooking liquid.
Flour
Thickens the cream mixture so it clings to the onions instead of running thin.
Sugar
Adds a touch of sweetness that balances the savory onions.

The step that matters

Letting the cream mixture boil. Flour needs to reach a boil to fully thicken and lose its raw starchy taste. Boiling too gently leaves the sauce thin and floury, while stirring it into hot cream first helps prevent lumps.

Swap the onion

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

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

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