Why it works: Vinegar and pepper are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

What each ingredient does
- Eggs
- Set firm during boiling, forming the cooked white and yolk that the dish is built on.
The step that matters
Boil the eggs for 10 minutes. Boiling time controls how set the yolk becomes. Too short leaves the yolk runny, while too long can leave a grey-green ring around it from iron and sulfur reacting at the yolk surface. Moving the eggs to cold water quickly stops further cooking and makes the shells easier to peel.
