Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

What each ingredient does
- Eggs
- Whipped whites give the omelet its light, airy structure, while the yolks add richness and set during cooking.
- Butter
- Melted in the pan, it adds fat and flavor and helps keep the omelet from sticking.
- Watercress
- Adds a fresh, peppery flavor and a little moisture to the folded omelet.
The step that matters
Folding the yolks into the whites. Whipped egg whites hold air only when handled gently. Stirring or deflating them too much releases that air, leaving a flat, dense omelet.
