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

What each ingredient does

Bread
Provides a crisp, sturdy base that holds the melted cheese.
Gloucester cheese
Melts and browns into a savoury, rich topping that forms the main body of the dish.
Butter
Adds fat that toasts the bread golden and carries savoury flavour.
Mustard
Adds sharp, pungent flavour that cuts through the richness of the melted cheese.

The step that matters

Toasting the cheese side until browned. Cheese needs enough heat to melt into an even layer and brown for flavour, but too much heat burns the surface before the centre softens. Watch the colour closely and keep the heat moderate.

Swap the mustard

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

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

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