Directions
Prepare

Shared aroma: 2-nonenal (fatty, green).
Egg and pepper barely smell alike, yet cooks put them together in 50,580 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Egg yolks
- Emulsifier: lecithin in the yolks helps hold the oil and water together in a stable, creamy mixture.
- Salad oil
- Fat that supplies the body, richness, and thick texture of the finished sauce.
The step that matters
Adding the oil slowly at the start. Oil must be dispersed into tiny droplets around the yolk proteins to form an emulsion. Adding too much oil too quickly overwhelms the yolks, so the mixture can split and fail to thicken. Adding the first teaspoons gradually lets the emulsion establish itself.
