Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing and bind it into a creamy emulsion.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavour.
- Butter
- Adds richness and a smooth, mellow mouthfeel to the dressing.
- Sugar
- Balances the acidity with sweetness.
- Mustard
- Adds sharpness and helps stabilise the emulsion.
The step that matters
Stirring the hot mixture into the egg yolks. Adding hot liquid too fast can scramble the egg yolks. Pour slowly while beating constantly so the yolks warm gradually and thicken smoothly instead of curdling.
Swap the celery
How well each one fits the dish's main ingredients (vinegar, mustard, butter, egg, sugar):
- Capersfits better
- Tarragonfits better
- Cinnamonfits better
- Celerythe original
