Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Forms the base that holds the topping and crisps when fried.
- English cheese
- Melts into a creamy layer that binds the toast together.
- Ham
- Adds savoury, salty flavour to the cheese topping.
- Butter
- Browns the bread surface and adds rich flavour during frying.
- Mustard
- Adds sharp, pungent flavour that cuts the richness of the cheese.
The step that matters
Fry without turning. Leaving the toasts undisturbed lets the underside brown and crisp while the topping softens. Turning too early can slide the cheese off and break the crust.
