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
- Red chilies
- Provide the main heat and pepper flavor that infuses into the vinegar.
- Vinegar
- Acts as the infusing liquid, extracting chili flavor and heat over time.
- Cayenne pepper
- Adds extra heat and pungency, used optionally to adjust spiciness.
The step that matters
Infuse the chilies in the vinegar for two weeks. Capsaicin and other flavor compounds dissolve slowly into the acidic liquid, so the full heat and flavor develop only with sufficient steeping time. Cutting or crushing the chilies first exposes more surface area, speeding extraction.
