Why it works: Pepper and cabbage are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 4,081 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Keep French Beans All the Year
Ingredients
Directions
Preserve the beans
Gather young beans on a fine day.
In a large stone jar, layer salt and beans until full, covering with salt.
Tie a coarse cloth over the jar and place a weight on top to keep out air. Store in a dry cellar.
Prepare and cook
When ready to use, wash beans and soak in soft water for 24 hours, changing water often.
Boil beans with the white heart of a small cabbage without adding salt. Drain and chop the cabbage, then combine with beans in a saucepan.
Add butter rolled in flour, a little pepper, and gravy. Let stew for 10 minutes and serve as a side dish.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young french beans
- Form the main body of the dish, preserved in salt and then softened for cooking.
- Coarse sea salt
- Preserves the beans by drawing out moisture and keeping air and spoilage away.
- Butter
- Adds richness and fat, giving the stew a smooth, rounded texture.
- Flour
- Thickens the butter and the cooking liquid so the stew becomes less watery.
- Good gravy
- Adds savoury moisture and flavour to the stewed beans.
The step that matters
Soaking the preserved beans. The beans are packed heavily in salt, so soaking them for a full 24 hours with frequent water changes removes excess salt. Skipping or shortening this leaves the dish too salty.
Swap the cabbage
How well each one fits the dish's main ingredients (beans, butter, egg, flour, pepper):
- Chivefits better
- Asparagusfits better
- Spinachfits better
- Cabbagethe original
Fit is the average pairing score against beans, butter, egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
