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 soft and sweet as they cook slowly.
Cream sauce
Adds richness and a smooth, creamy coating over the cooked onions.

The step that matters

Trim the roots without cutting them. Cutting into the root end can let the onion fall apart during the long simmer, while leaving the base intact helps each onion hold its shape and stay whole.

Swap the onion

How well each one fits the dish's main ingredients (cream, sauce):

  1. Horseradishfits better
  2. Mustardfits about as well
  3. Spinachfits about as well
  4. Onionthe original

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