Why it works: Egg and beans are a kitchen classic. They rank in the top 32% of all ingredient pairs, and cooks put them together in 2,030 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Pickled Beans
Ingredients
Directions
Make the brine
Boil the water with salt for 10 minutes, then let it cool.
Pick the beans before they become stringy and place them whole in an earthenware crock.
Pour the cooled pickle over the beans.
Ferment and store
Cover the beans with a piece of wood and a heavy weight to keep them submerged.
Store in a dry place for up to 7 months, rinsing the cloth covering every two weeks in boiling and then cold water.
Prepare to serve
When ready to use, soak the beans for 6 hours, changing the water once or twice, then cut and boil them like fresh beans.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French beans or scarlet runners
- The vegetable being preserved; it softens and turns tender-crisp during the long brine storage.
- Coarse sea salt
- Draws water out of the beans and inhibits spoilage microbes, letting the brine ferment and preserve them.
The step that matters
Keep the beans fully submerged under the brine. Beans exposed to air can grow mold and spoil. A weight and wooden cover hold them under the brine, where the salt and the fermentation keep them safe for months.
