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 ↓

Directions
Make the soup
In a soup pot, combine bacon, grated carrots, cabbage stock, and bay leaf.
Cook for 25 minutes, then skim the surface and remove the bay leaf.
Add pepper and salt.
Finish and serve
In a bowl, rub together butter and flour, then add to hot milk.
Pour the mixture into the soup and bring to a boil.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Adds savory fat and smoky flavor to the stock.
- Butter
- Enriches the soup and, with flour, forms a thickening base.
- Flour
- Thickens the soup, giving it a smoother body when mixed with butter.
- Milk
- Adds creaminess and body to the soup.
- Carrots
- Add natural sweetness and color to the soup.
The step that matters
Adding the butter and flour mixture to the milk. Flour clumps if it is dropped into hot liquid unmixed. Rubbing it with butter first coats the starch grains so they disperse evenly, and the mixture then thickens smoothly as it heats.
Swap the cabbage
How well each one fits the dish's main ingredients (carrot, pepper, butter, flour, milk):
- Parsnipfits better
- Potatofits better
- Capsicumfits better
- Cabbagethe original
Fit is the average pairing score against carrot, pepper, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
