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
- Eggs
- Proteins set as the mixture cooks, thickening it into a smooth, creamy dressing.
- Vinegar
- Provides the sharp acidity that gives the dressing its tang.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
- Flour
- Starch swells with heat and helps thicken the dressing.
- Oil
- Adds fat for richness and a smoother mouthfeel.
- Mustard
- Contributes sharp flavor and helps the dressing taste balanced.
The step that matters
Cook over medium heat, stirring constantly. Egg proteins and flour starch thicken as they heat. If the heat is too high or the mixture is not stirred, the eggs can scramble and form lumps, leaving the dressing grainy instead of light and smooth.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, pepper, flour, sugar):
- Capsicumfits about as well
