Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Provides the main flavour and, when melted, a rich, stretchy body that holds the topping together.
- Egg
- Yolk binds the mixture and adds richness and smoothness so it spreads and sets evenly.
- Butter
- Adds fat for a smooth, moist texture and helps the mixture brown lightly.
- Mushroom ketchup
- Adds savoury, umami depth that rounds out the cheese flavour.
The step that matters
Brown the toast before the fire. Browning depends on heat and time; too little and the topping stays pale and raw-tasting, too much and the cheese scorches and turns bitter. Watch closely as the topping colours.
