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 it body, richness and its main flavour.
- Butter
- Adds fat that helps the cheese melt smoothly and combine without clumping.
- Egg yolk
- Acts as an emulsifier and thickener, helping the sauce become smooth and creamy.
- Madeira wine
- Adds acidity and aromatic depth that balances the richness of the cheese.
The step that matters
Gradually add the egg yolk and wine mixture. Adding the egg yolk too quickly over heat can scramble it, leaving lumps. Adding it slowly while stirring lets the yolk emulsify into the melted cheese for a smooth sauce.
