Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and helps the bread brown and crisp while frying.
- English cheese
- Melts over the bread to form a savory, binding topping.
- Ham
- Adds savory, salty flavor to the topping.
- Mustard
- Adds sharp, tangy flavor that balances the rich cheese and butter.
The step that matters
Fry without turning. Frying in butter without turning lets one side brown and crisp while the topping stays on top. Turning can knock off the cheese and ham and break the squares apart.
Swap the mustard
