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
- Set and thicken the dressing as they cook, giving it body like a custard.
- Cream or sweet milk
- Adds moisture and richness, softening the sharpness of the vinegar.
- Vinegar
- Adds acidity that gives the dressing its tangy flavor.
- Melted butter
- Adds fat for richness and a smooth, silky texture.
- Mixed mustard
- Adds sharp, savory flavor that balances the richness of the eggs and butter.
The step that matters
Cook the mixture like custard until thickened. Egg proteins set as they heat and thicken the dressing, but if the heat is too high they overcook and curdle into lumps. Cook gently and stir constantly until it coats a spoon.
Swap the mustard
