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 as they cook and give it a smooth, rich body.
- Cider vinegar
- Adds acidity that sharpens the flavor and balances the sugar and butter.
- Butter
- Adds fat that gives the dressing a silky, smooth mouthfeel.
- Sugar
- Adds sweetness to balance the acidity of the vinegar.
- Mustard
- Adds sharp flavor and helps emulsify the dressing.
The step that matters
Cook over hot water until thick. Egg yolks set at gentle heat and can scramble if overheated. Cooking over hot water, not direct heat, lets the dressing thicken smoothly without curdling.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, cider, vinegar, butter):
- Mustardthe original
- Capsicumfits about as well
- Cucumberfits less well
- Shallotfits less well
Fit is the average pairing score against egg, sugar, cider, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
