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 ↓
Egg Soup
Ingredients
Directions
In a pot, combine the water, beaten egg yolk, butter, and sugar.
Heat over medium heat, stirring until it begins to simmer.
Pour the mixture several times from the pot to a basin and back again until it is smooth and frothy.

What each ingredient does
- Egg yolk
- Thickens the soup as its proteins set with gentle heat, giving body and richness.
- Butter
- Adds fat for a rich, smooth mouthfeel.
- Sugar
- Adds sweetness that balances the richness of the yolk and butter.
The step that matters
Heating while stirring. Egg yolk proteins set when heated, so heating too fast or without stirring can scramble the yolk into lumps. Keeping the heat moderate and stirring constantly lets the mixture thicken smoothly. Pouring it back and forth afterward helps break up any small lumps and makes it frothy.
