Why it works: Pepper and vinegar 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the whites that hold the filling and the mashed yolks that form it.
- Butter
- Adds richness and a smoother, creamier texture to the mashed yolks.
- Vinegar
- Adds a bright acidity that balances the richness of the yolk filling.
The step that matters
Boil the eggs until the yolks are mealy. Overcooked yolks turn dry and grey-rimmed with a chalky texture, while undercooked yolks stay too runny to mash into a filling. Timing the boil controls how the yolk sets.
“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.
