Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Directions
Make the base
In a bowl, mix the dry mustard, salt, and powdered sugar with enough hot water to combine.
Slowly pour in the oil while beating continuously until fully incorporated.
Add the three unbeaten eggs and beat everything together.
Stir in the vinegar and milk.
Cook and serve
Place the mixture over a double boiler and bring to a boil, stirring constantly.
Strain if desired before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they cook, giving it a creamy body.
- Oil
- Adds fat that makes the dressing rich and smooth when beaten in.
- Vinegar
- Provides sharp acidity that balances the richness and sweetness.
- Milk
- Adds moisture and mild richness, softening the dressing's tang.
- Dry mustard
- Contributes a sharp, pungent flavour that gives the dressing its character.
The step that matters
Cooking the mixture over a double boiler. Egg proteins thicken gently with steady, constant stirring over indirect heat. Too much heat or too little stirring can scramble the eggs and leave lumps, so the dressing must be stirred continuously while it thickens.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, egg, vinegar, milk):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Sweet potatofits about as well
Fit is the average pairing score against sugar, egg, vinegar, milk. Candidates are from the same food group and used in at least 100 recipes.
