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.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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 as they set during cooking and bind it into a smooth emulsion.
- Oil
- Adds richness and body, and helps form a smooth emulsion with the eggs.
- Flour
- Thickens the liquid so the dressing becomes creamy and holds together.
- Vinegar
- Adds the sharp acidity that gives the dressing its tang.
- Sugar
- Balances the acidity of the vinegar and mustard with a touch of sweetness.
The step that matters
Cook in a double boiler until thickened. Gentle, indirect heat lets the egg proteins and flour starch thicken the dressing slowly. Overheating can curdle the eggs, so the mixture should be stirred and cooked only until it coats a spoon.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, flour, pepper, egg, vinegar, milk):
- Capsicumfits better
- Mustardthe original
- Shallotfits about as well
- Arrowrootfits about as well
Fit is the average pairing score against sugar, flour, pepper, egg, vinegar, milk. Candidates are from the same food group and used in at least 100 recipes.
