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 ↓

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 cook, giving it a smooth, rich body.
- Vinegar
- Adds acidity that sharpens the flavour and balances the sweetness.
- Flour
- Stabilises the mixture and helps it thicken without breaking.
- Whipped cream
- Thins the cooked dressing and adds a light, creamy texture.
The step that matters
Cook until thick, stirring constantly. Egg proteins set as they heat, so the dressing can curdle or scramble if it overheats or stops being stirred. Constant stirring keeps the heat even and yields a smooth, thick result.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, flour, pepper, vinegar, egg, cream):
- Capsicumfits about as well
- Mustardthe original

Fit is the average pairing score against sugar, flour, pepper, vinegar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
