Why it works: Cabbage and pepper 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
- Milk
- Forms the liquid base and gives the soup a creamy body.
- Butter
- Adds richness and flavour as it coats the cabbage before the liquid goes in.
- Flour
- Thickens the soup as its starch swells when heated in the liquid.
- Cabbage
- Provides the main vegetable body, and gentle cooking softens its texture.
The step that matters
Blending the flour before it goes in. Flour must be blended smoothly with cold water before stirring in, because dry flour clumps in hot liquid. Once in, the soup must boil gently so the starch swells fully and thickens.
Swap the cabbage
How well each one fits the dish's main ingredients (milk, butter, flour, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Cabbagethe original
Fit is the average pairing score against milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
