Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soft cheese
- Melts into the sauce and provides the main flavour and creamy body.
- Eggs
- Thicken the cheese mixture as they set gently with the heat, giving it body.
- Milk
- Loosens the mixture so it spreads smoothly and stays creamy rather than grainy.
The step that matters
Stir the mixture over low heat until the cheese is melted. High heat can make cheese tight and grainy, and it can scramble the eggs. Gentle, steady heat lets the cheese melt evenly into a smooth sauce while the eggs thicken it slowly.
