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

What each ingredient does

Gruyere cheese: Melts and provides the rich, savoury flavour that dominates the sandwich.
White bread: Forms the structure that holds the filling together.
Butter: Adds fat and richness to the bread and helps it brown lightly.
French mustard: Adds sharp, tangy flavour that balances the richness of the cheese.
