Why it works: Mustard and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 859 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Salad Dressing
Ingredients
Directions
Make the dressing
Pound the yolks of the hard-boiled eggs smoothly.
Mix in the mustard, powdered sugar, and coarse sea salt.
Gradually add the cream or oil and vinegar, mixing well.
Adjust salt and vinegar to taste.
For added flavor, incorporate chili or cayenne vinegar, shallot vinegar, or other flavorings as desired.
Finish and rescue
Rub the salad bowl with a cut clove of garlic for a subtle flavor.
If the mixture curdles, add the yolk of a fresh raw egg to smooth it out.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Their fat and emulsifying lecithin bind the oil and vinegar into a smooth, thick dressing.
- Mustard
- Its natural emulsifiers help hold the oil and vinegar together and add sharpness.
- Cream or oil
- Supplies fat that gives the dressing body, richness, and a smooth mouthfeel.
- Vinegar
- Adds acidity that brightens the flavor and balances the richness of the fat.
- Powdered sugar
- Adds a little sweetness that softens the sharpness of the vinegar and mustard.
The step that matters
Adding the cream or oil gradually. Oil added too fast to the yolk mixture can break the emulsion and curdle the dressing. Adding it slowly lets the yolk lecithin coat each droplet, producing a stable, smooth emulsion.
Swap the shallot
The recipe marks shallot as optional. How well each one fits the dish's main ingredients (egg, mustard, sugar, cream, vinegar, caviar, clove):
- Horseradishfits about as well
