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

What each ingredient does

Bread
Forms the base that holds the melted cheese and soaks up its topping.
Butter
Adds fat and richness and helps the bread toast to an even golden color.
Cheese
Melts and browns on top, supplying the main savory flavor and stretchy texture.

The step that matters

Toasting the cheese side under the salamander or broiler. Cheese melts and browns quickly under strong direct heat. Too little heat leaves it cold and stiff, while too long makes it dry, oily, or burnt. Watch it closely and remove it as soon as it is bubbling and lightly browned.

Swap the mustard

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

  1. Tomatofits better
  2. Potatofits about as well
  3. Onionfits about as well
  4. Mustardthe original

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