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 ↓

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 beans
- Form the main body of the dish, becoming tender after soaking and stewing.
- Coarse salt
- Draws water out of the beans during preservation, keeping them from spoiling in the jar.
- Butter
- Adds richness and fat, and with flour forms a roux that thickens the stew.
- Flour
- Combined with butter to thicken the stewing liquid into a smooth sauce.
- Gravy
- Supplies liquid and savoury flavour that the beans and cabbage absorb while stewing.
The step that matters
Soaking the preserved beans. Salted beans must soak long enough, with frequent water changes, to remove excess salt; otherwise the finished dish stays too salty.
Swap the cabbage
How well each one fits the dish's main ingredients (beans, butter, flour, pepper):
- Okrafits better
- Sweet potatofits better
- Chivefits better
- Cabbagethe original
Fit is the average pairing score against beans, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
