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

What each ingredient does

Cheese
Melts into a smooth, rich sauce that coats the bread and carries the flavour.
Ale
Thins the melting cheese and adds a light, malty flavour.
Bread
Provides a crisp, toasted base that holds the melted cheese.

The step that matters

Heat the cheese until just melted. Cheese turns stringy, oily or grainy if overheated, so it should be heated gently only until it melts and becomes smooth.

Swap the mustard

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

  1. Capsicumfits better
  2. Tomatofits better
  3. Mustardthe original
  4. Spinachfits about as well

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