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

What each ingredient does

Onions
Provide the bulk and sweet, mellow flavor as they soften during boiling and baking.
Butter
Adds richness and helps the top crumbs brown in the oven.
Bread crumbs
Form the layers and crisp to a browned topping that contrasts with the soft onions.

The step that matters

Bake until the bread crumbs are brown. Baking time alone is not a reliable signal, so the top should be checked for color. Browning comes from the Maillard reaction and dry crumbs, which gives the dish its crisp, savory crust.

Swap the onion

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

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

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