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 ↓
Handy Salad Dressing
Ingredients
Directions
Make the dressing
Heat the vinegar slightly.
Add the well-beaten yolks and beat constantly until it thickens a little.
Remove from heat and add the butter and seasoning, beating well until it cools slightly.
Finish and store
Whip the cream until stiff and add about ¼ of the dressing, beating until smooth.
Mix the whipped cream into the salad and save a spoonful to top each portion served.
Store any remaining dressing in a covered jar in a cool place for several weeks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they cook gently with the warm vinegar, giving it body.
- Butter
- Adds richness and a smooth, silky mouthfeel to the dressing.
- Vinegar
- Provides acidity that gives the dressing its tangy flavour.
- Thick cream
- Whipped into the dressing, it lightens the texture and mellows the sharpness.
The step that matters
Thickening the yolks over heat. Egg yolks thicken when gently heated, but if they get too hot they can scramble into lumps. Beating constantly spreads the heat evenly and keeps the dressing smooth.
