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 ↓
Mayonnaise Dressing
Ingredients
Directions
Beat the yolks of three eggs until thick and creamy.
Add salt, sugar, paprika, mustard, butter, flour, and vinegar.
If the vinegar is too strong, dilute it.
For a variation, mix with 1 tablespoon of whipped cream for every 2 tablespoons of dressing.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the dressing and help hold its liquid and fat together smoothly.
- Vinegar
- Adds acidity for a sharp, tangy flavour and helps balance the richness.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
- Flour
- Its starch thickens the mixture slightly, giving it more body.
The step that matters
Beat the yolks until thick and creamy. Well-beaten yolks trap air and build body before the other ingredients are added. If they are under-beaten, the base stays thin and the finished dressing will be loose.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, butter, flour, vinegar):
- Shallotfits about as well
- Mustardthe original
- Chivefits about as well
- Cucumberfits about as well
Fit is the average pairing score against egg, sugar, butter, flour, vinegar. Candidates are from the same food group and used in at least 100 recipes.
