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 creamy topping and browns under heat, giving the sandwich its main flavor.
- Bread
- Provides a crisp toasted base that holds the melted cheese.
- Butter
- Adds richness and helps the toasted bread brown and taste savory.
- Mustard
- Adds sharp acidity that cuts through the rich, melted cheese.
The step that matters
Toasting the other side of the cheese. The cheese must be heated until it bubbles and browns without drying out or burning. Too little heat leaves it cold and stiff, while too much makes it greasy and scorched, since the proteins and fats in cheese change quickly under high heat.
Swap the mustard
How well each one fits the dish's main ingredients (bread, cheese, butter):
- Tomatofits better
- Potatofits about as well
- Onionfits about as well
- 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.
