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 to give its body, savoury flavour and stretch.
- Butter
- Adds fat that carries flavour and keeps the cheese smooth and glossy.
- Egg yolks
- Thicken the sauce as they set and bind it into a smooth mass.
- Cream
- Adds richness and a softer, smoother texture to the melted cheese.
- Onions
- Soften when stewed, adding sweetness and a mellow aroma to the sauce.
The step that matters
Simmer gently until the cheese is dissolved. High heat tightens cheese proteins and can squeeze out fat, leaving the sauce grainy or oily. Gentle heat lets the cheese melt evenly into a smooth emulsion.
