Why it works: Butter and egg 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 ↓

Ingredients
Directions
Fry the eggs
Melt the butter in an omelet pan over medium heat.
Carefully break the eggs into the pan, keeping the yolks intact.
Season with pepper and coarse sea salt.

Stir in the vinegar and boil for a few seconds.
Pour the brown butter sauce over the fried eggs and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set to form the main body of the dish, with yolks left intact for a soft centre.
- Butter
- Provides fat for frying and, once browned, a nutty aroma for the sauce.
- Vinegar
- Adds acidity that sharpens the rich, buttery brown butter sauce.
The step that matters
Let the butter brown without burning. Butter milk solids turn nutty and brown as the water cooks off, but they burn quickly once the butter darkens too far. Watch the colour closely and remove it from the heat at the first deep golden-brown stage, so the sauce tastes toasty rather than bitter.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
