Ingredients
Directions
Make the cheese mixture
Cut the cheese into very thin slices and place in a saucepan.

Stir constantly over medium heat until the cheese melts.
Beat the eggs and mix with the remaining milk.

Serve on toast

Serve on a hot dish and sprinkle with additional cayenne if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the cheese mixture as they cook, giving it a soft, set texture.
- Cheese
- Melts to form the creamy base of the topping and provides rich flavour.
- Milk
- Loosens the melted cheese and keeps the mixture smooth and spreadable.
- Butter
- Adds richness and smooth mouthfeel to the cheese mixture.
The step that matters
Stirring the egg mixture into the melted cheese. Eggs thicken when heated, so adding them to very hot cheese without constant stirring can cause curdling or scrambling. Stir steadily and keep the heat moderate to keep the mixture smooth.
