Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Coagulate with gentle heat to thicken the dressing and give it body.
- Butter
- Adds richness and a smooth, velvety mouthfeel to the dressing.
- Vinegar
- Adds acidity that brightens the flavor and balances the sugar and yolks.
- White sugar
- Adds sweetness that balances the sharp vinegar.
- Milk
- Adds moisture and loosens the mixture into a pourable dressing.
The step that matters
Stir constantly over hot water until it thickens. Egg yolks thicken as their proteins set with gentle heat. If the heat is too high or the mixture is left unstirred, the yolks can scramble and turn grainy instead of smooth.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, pepper, butter, vinegar, milk):
- Capsicumfits better
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against egg, sugar, pepper, butter, vinegar, milk. Candidates are from the same food group and used in at least 100 recipes.
