Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the dressing as they heat, giving it body.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Milk or cream
- Adds moisture and mildness, softening the sharpness of the vinegar.
- Vinegar
- Adds acidity, giving the dressing its tangy bite.
- Mustard
- Adds sharp flavour that balances the richness of the butter and eggs.
The step that matters
Scald the combined mixture over boiling water, stirring continuously until thick.. Egg proteins thicken gently with heat, but too much heat or too little stirring can scramble them. Constant stirring over steady, moderate heat keeps the dressing smooth and evenly thickened.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, butter, milk, egg, sugar, pepper):
- Capsicumfits better
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against vinegar, butter, milk, egg, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
