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 add richness as they set with gentle heat.
- Butter
- Adds fat and richness, giving the dressing a smooth, silky mouthfeel.
- Vinegar
- Provides acidity that sharpens the dressing and balances the sweetness.
- Cornstarch
- Thickens the dressing as it heats, helping it reach a spoonable consistency.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar and mustard.
The step that matters
Stir the dressing over heat until it begins to thicken. Egg yolks can scramble if overheated. Gentle, constant stirring in a double boiler lets the yolks and cornstarch thicken the dressing smoothly without curdling.
Swap the nuts
How well each one fits the dish's main ingredients (banana, lettuce, mustard, butter, sugar, cream, egg):
- Almondfits better
- Chestnutfits better
- Hazelnutfits better
- Nutsthe original
Fit is the average pairing score against banana, lettuce, mustard, butter, sugar, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
