Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Salad Dressing Without Oil
Ingredients
Directions
Make the dressing
In a bowl, combine the mashed egg yolks, beaten raw eggs, dry mustard, sugar, white wine vinegar, lemon juice, and melted butter.
Beat the mixture until very light and fluffy.
Season with salt and pepper to taste.
Thicken and adjust
Transfer the mixture to a double boiler and continue to beat while it thickens.
If the dressing is too thick, add a little cream to reach the desired consistency.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Add body and a smooth, rich texture as they emulsify into the dressing.
- Raw eggs
- Provide structure and thickening as their proteins set when gently heated while beaten.
- Melted butter
- Adds fat and richness, giving the dressing a silky mouthfeel.
- White wine vinegar
- Supplies acidity that brightens the flavor and balances the richness.
- Dry mustard
- Acts as an emulsifier helping the fat and liquids stay blended.
The step that matters
Thickening over the double boiler. Egg proteins set as they warm, so heat must stay gentle and the mixture must be beaten constantly. Too much heat scrambles the eggs and the dressing curdles instead of thickening smoothly.
Swap the mustard
