Why it works: Peas and lemon are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 1,005 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Bottled Peas
Ingredients
Directions
Prepare
Wash the pea pods thoroughly in cold water or a very weak solution of potassium permanganate.
Shell the peas and blanch them in boiling water for 1-2 minutes, depending on their size.
Dip the peas in cold water for 1 minute.
Pack and sterilize
Pack the peas loosely into jars, leaving 1 inch from the top, and cover completely with brine.
Place the jars in a sterilizer and bring to 212°F (100°C) as quickly as possible.
Maintain this temperature for 1.5 hours.
If necessary, top up with boiling brine and re-sterilize for 20 minutes.
Finish
Cool, test, and store the jars.

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.

What each ingredient does
- Green peas
- Form the main body of the canned product, providing the vegetable texture and flavor.
- Lemon brine
- Covers the peas in the jars, carrying flavor and keeping the peas submerged during sterilizing.
The step that matters
Maintain the sterilizer temperature for the full time. Peas are low-acid, so the jars must reach and hold 212°F for the full period to destroy spoilage microbes. Shortening the time or letting the temperature drop can leave the jars unsafe to store.
