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 ↓
Bottled Salad Dressing
Ingredients
Directions
Make the dressing
Beat the yolks of the eggs in a large bowl.
Add the black pepper, sugar, salt, cream, mustard, and cayenne to the egg yolks and mix thoroughly.
Heat the vinegar in a saucepan and add the butter, stirring until melted.
Bring the vinegar and butter mixture to a boil, then pour it over the egg mixture while stirring well.
Cool and store
Allow the dressing to cool, then bottle it and store in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks emulsify and thicken the dressing as they are gently heated, giving it body.
- Butter
- Adds fat and richness, softening the sharpness of the vinegar.
- Vinegar
- Provides the acidity that gives the dressing its tang and helps keep it stable.
- Cream
- Adds fat and smoothness, rounding out the texture of the dressing.
- Sugar
- Balances the acidity of the vinegar with sweetness.
The step that matters
Pouring the hot vinegar and butter mixture over the egg mixture. Egg yolks can scramble if they meet very hot liquid too quickly. Pouring slowly while stirring constantly tempers the eggs so the dressing thickens smoothly instead of curdling.
