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 ↓
Dressing for Cold-slaw
Ingredients
Directions
In a bowl, mix together the sugar, salt, mustard, and warm water until smooth.
Stir in the oil.
Heat the mixture over medium heat until it boils, stirring steadily.
Remove from heat and gradually beat it into the beaten eggs in a separate bowl.
Return the sauce to the heat, setting it over boiling water.
Stir until smooth and thick, then add the vinegar.
Allow to cool before using for slaw or cold meats.

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 gently, giving it body and a creamy texture.
- Vinegar
- Adds acidity that brightens the dressing and balances its richness and sweetness.
- Oil
- Adds fat that makes the dressing smooth and rich-tasting.
- Dry mustard
- Adds sharp, pungent flavor that complements the eggs and vinegar.
The step that matters
Return the sauce to the heat over boiling water. Eggs can scramble if exposed to direct high heat. Gentle heat over simmering water thickens the sauce slowly and evenly, while stirring until smooth and thick keeps it creamy rather than curdled.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, egg, vinegar, cream):
- Mustardthe original
- Cucumberfits about as well
- Capsicumfits about as well
- Horseradishfits about as well
Fit is the average pairing score against sugar, egg, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
