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 ↓
Eggs with Black Butter
Ingredients
Directions
Melt the butter in a chafing dish until it turns dark brown, almost black.
Carefully break in the eggs one at a time, ensuring they do not run together.
Baste the eggs with the butter until cooked to your liking.
Add the vinegar just before removing the eggs from the heat.
Sprinkle with salt and pepper before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Browns into nutty, aromatic black butter that coats and flavours the eggs.
- Eggs
- Set in the hot butter to form the main body of the dish.
- Vinegar
- Adds a sharp acidity that cuts through the rich, nutty butter.
The step that matters
Breaking in the eggs one at a time. Eggs spread and run together if crowded or added too fast. Adding them singly keeps each egg whole and evenly basted in the hot butter.
