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 ↓

Ingredients
Directions
Beat the hard boiled egg yolks in a bowl.
Mix in the table salt, raw mustard, soft sugar, and cayenne pepper until well combined.
Slowly add the cream or milk while mixing continuously.
Gradually add the vinegar until the dressing thickens.
Optionally, rub the bowl with garlic or onion for added flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard boiled egg yolks
- Emulsify with the liquids and give the dressing a thick, creamy body.
- Cream or milk
- Adds moisture and richness, loosening the yolks into a smooth dressing.
- Vinegar
- Adds acidity that sharpens flavor and helps the dressing thicken as it is added.
- Raw mustard
- Its natural emulsifiers help hold the oil-free dressing together and add sharp flavor.
The step that matters
Add the cream or milk slowly while mixing. Adding liquid too fast can cause the yolk mixture to separate instead of forming a smooth, cohesive emulsion. Steady, continuous mixing keeps the fat and water evenly dispersed.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, pepper, cream, vinegar):
- Capsicumfits about as well
- Mustardthe original
- Horseradishfits about as well
- Spinachfits less well
Fit is the average pairing score against egg, sugar, pepper, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
