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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Thicken the dressing and add richness as they set with heat.
- Flour
- Thickens the melted butter so the dressing becomes smooth and body-rich.
- Vinegar
- Adds sharpness that balances the sweetness and richness of the dressing.
- Sugar
- Adds sweetness to balance the acidity of the vinegar.
The step that matters
Stir continuously until the dressing thickens. Egg proteins can scramble and curdle if the mixture overheats or sits still, while constant stirring keeps heat even. Flour starch also settles on the bottom of the pan and can scorch if not moved.
Swap the mustard
How well each one fits the dish's main ingredients (butter, flour, sugar, egg, vinegar):
- Shallotfits about as well
- Mustardthe original
- Chivefits about as well
- Cucumberfits about as well
Fit is the average pairing score against butter, flour, sugar, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
