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 ↓

Make the dressing
In a saucepan, combine vinegar and butter. Heat until boiling.
In a bowl, beat the egg yolks with cream, sugar, and mustard until light.
Slowly add the egg mixture to the boiling vinegar, stirring constantly until it boils again.
Remove from heat and beat until cool.
Finish

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify and thicken the dressing as they cook, giving it a rich, smooth body.
- Butter
- Adds fat for a rich mouthfeel and smooth texture.
- Cream
- Adds moisture and richness, softening the dressing's texture.
- Sugar
- Adds sweetness to balance the sharp vinegar.
- Vinegar
- Adds acidity that gives the dressing its tang.
- Whipped cream
- Lightens the dressing and adds airy, creamy body when folded in.
The step that matters
Adding the egg mixture to the boiling vinegar. Egg yolks scramble if they get too hot too fast. Adding the mixture slowly while stirring constantly tempers the eggs, so the dressing thickens smoothly instead of curdling.
Swap the mustard
