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 a weak brine by dissolving coarse sea salt in boiling water.
Soak the bell peppers in the brine for three mornings, pouring off the brine each time.
If you want the peppers to remain green, soak them in a mixture of vinegar and water with a bit of alum for a few days.
If you prefer them not green, boil a mixture of vinegar and water, then pour it over the peppers and let it cool.
Once cooled, submerge the peppers in strong, cold vinegar and seal tightly.
