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 ↓

Ingredients
Directions
Make the dressing
Scald the cream in a saucepan.
Stir in the butter and vinegar.
Beat the egg yolks in a bowl and add them to the cream mixture, stirring well to prevent curdling.
Cook until thickened, then remove from heat.
Finish and serve
Let it cool, then mix in the mustard, cayenne pepper, and salt.
Optionally, beat the egg whites until light and fold them into the mixture when cold.
For added flavor, include a little extract of celery.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the cream as they cook, giving the dressing its body.
- Butter
- Adds richness and a smooth, silky mouthfeel to the dressing.
- Rich cream
- Provides the fat and body that make up most of the dressing.
- Vinegar
- Adds acidity that sharpens the flavor and balances the richness.
- Mixed mustard
- Contributes sharp flavor and helps emulsify the dressing.
The step that matters
Adding the yolks to the hot cream. Egg yolks scramble and curdle if they meet hot liquid too quickly. Beating them first and stirring constantly while adding them to the cream keeps the mixture smooth as it thickens.
Swap the mustard
