Why it works: Pepper and lemon 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 ↓
Mayonnaise Sauce
Ingredients
Directions
Make the mayonnaise
Place the egg yolks in a bowl and season with pepper and salt.
Gradually add the salad oil drop by drop while stirring continuously until thickened.
Add the vinegar in the same manner, maintaining the desired consistency.
Incorporate a squeeze of lemon juice to whiten the sauce.
Finish and serve
Before serving, melt the aspic jelly (do not warm) and stir it into the mayonnaise until fully combined.

Egg and lemon barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifiers that bind the oil and vinegar into a stable, thick sauce.
- Salad oil
- Supplies the fat that, dispersed into the yolks, builds the sauce's body and richness.
- French vinegar
- Adds acidity that sharpens flavor and helps set the emulsion's consistency.
- Clear aspic jelly
- Gelatin-based addition that stiffens the sauce and adds a glossy, set texture.
The step that matters
Adding the oil drop by drop. Oil added too quickly cannot be absorbed by the egg yolk emulsifiers, so the sauce breaks and separates into a greasy liquid. Slow addition while whisking lets tiny oil droplets stay suspended and the mixture thicken smoothly.
