Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce as they gently set over low heat, giving it body.
- Mustard
- Adds the sharp, pungent flavour that defines the sauce.
- Currant jelly
- Provides sweetness and fruity body that balances the vinegar.
- Vinegar
- Adds acidity that sharpens the flavour and keeps the sauce tangy.
- Sugar
- Sweetens the sauce and balances the acidity and heat.
The step that matters
Stirring over low heat. Egg yolks thicken when gently heated but can scramble if the heat is too high or they are left unstirred. Constant stirring over low heat keeps the sauce smooth while it thickens.
