Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts into the sauce and supplies the main savoury, rich flavour.
- Butter
- Adds fat for a smooth, glossy texture and richer mouthfeel.
- Milk
- Adds moisture so the melted cheese loosens into a spreadable sauce.
- Toasted bread
- Provides a crisp base that holds the warm cheese topping.
The step that matters
Heat the cheese mixture gently. High heat tightens the cheese proteins and makes the fat separate, leaving the sauce grainy, oily, or stringy. Low, steady heat lets the cheese melt evenly into a smooth sauce.
