Why it works: Vinegar and mustard 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Thickens the dressing as it cooks and binds it into a smooth emulsion.
- Egg white
- Adds lightness and body to the dressing when the cooked mixture is poured over it.
- Butter
- Adds richness and a silky texture to the dressing.
- Vinegar
- Provides the sharp acidity that gives the dressing its tang.
The step that matters
Add the beaten egg yolk and stir until thickened. Egg yolk proteins set as they heat, thickening the dressing. If the heat is too high or stirring is neglected, the yolk can scramble into lumps instead of forming a smooth, thick base.
Swap the walnut
How well each one fits the dish's main ingredients (vinegar, egg, mustard, sugar, butter, cream):
- Almondfits better
- Chestnutfits about as well
- Sesamefits about as well
- Walnutthe original
Fit is the average pairing score against vinegar, egg, mustard, sugar, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
