Prepare

Toast the unbuttered side of a slice of Gloucester cheese until golden.
Place the toasted side of the cheese on the buttered bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gloucester cheese
- Melts into a smooth, spreadable topping that forms the body of the dish.
- Bread
- Provides a crisp, sturdy base that holds the melted cheese.
- Butter
- Adds fat that helps the bread brown and gives a richer flavour.
- Made mustard
- Adds sharpness that cuts through the richness of the melted cheese.
The step that matters
Toast the top until the cheese melts and spreads. Cheese that is heated too gently stays stiff and does not spread, while overheating makes it oily and tough. Watching for a smooth, melted surface gives an even topping.
Swap the mustard
How well each one fits the dish's main ingredients (bread, cheese, butter, pepper):
- Capsicumfits better
- Tomatofits better
- Potatofits about as well
- Mustardthe original
Fit is the average pairing score against bread, cheese, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
