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 ↓
Pickled Peppers
Ingredients
Directions
Prepare
Slit the peppers on one side and remove the core.
Soak the peppers in a mixture of salt and water, changing the water often, for one week in a warm place.
Once the peppers turn yellow and then green, place them in a jar.
Pickle
Pour boiled vinegar over the peppers and add a pinch of alum.

What each ingredient does
- Peppers
- Provide the main vegetable that softens and takes on the pickling flavour.
- Boiled vinegar
- Adds acidity that preserves the peppers and gives them their sharp, tangy taste.
- Salt
- Draws water out of the peppers and helps firm and season them during soaking.
- Alum
- Helps the peppers stay firm and crisp during pickling.
The step that matters
Changing the salt water often during the soak. Fresh water keeps the brine salty enough to draw out moisture and limit spoilage over the week-long soak, so replacing it regularly matters.
