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 sauce that coats the toast and carries the flavour.
Round of bread
Provides a crisp, sturdy base that holds the melted cheese.
Mustard
Adds sharpness that balances the richness of the melted cheese.
Water or milk
Adds moisture so the cheese melts into a smooth, pourable mixture.

The step that matters

Heat the mixture gently while stirring until melted. Cheese proteins tighten and turn grainy or oily when overheated, so low heat and constant stirring keep the sauce smooth and cohesive.

Swap the mustard

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

  4. Mustardthe original

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