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 ↓
Salad Dressing
Ingredients
Directions
Make the dressing base
In a bowl, mix the mustard, sugar, and salt, adding water to create a smooth paste.
Add the beaten egg yolks, butter, and vinegar to the mixture.
Cook in a double boiler until thickened like custard.
Remove from heat and let cool before using.
Serve
To serve, fold the mixture into 1 cup of whipped cream until well combined.
Pour over any salad and mix gently.

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 into a custard as they cook and set, and add richness.
- Vinegar
- Adds acidity that sharpens the flavor and balances the sweetness and richness.
- Heavy cream
- Whipped and folded in at the end, it lightens the dressing and adds creamy body.
- Mustard
- Adds sharp flavor and helps emulsify the dressing.
The step that matters
Cook in a double boiler until thickened like custard. Egg yolks set when heated, but too much direct heat can scramble them. Gentle, indirect heat from a double boiler thickens the mixture smoothly without curdling.
Swap the walnut
How well each one fits the dish's main ingredients (mustard, sugar, butter, egg, vinegar, cream):
- Almondfits better
- Chestnutfits about as well
- Sesamefits about as well
- Walnutthe original
Fit is the average pairing score against mustard, sugar, butter, egg, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
