Why it works: Cabbage and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 3,001 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the bulk of the dish and becomes tender and soft during slow cooking.
- Onion
- Softens in hot fat and adds a sweet, savoury base flavour.
- Flour
- Dissolved in vinegar, it thickens the cooking liquid into a light sauce.
- Sugar
- Balances the sharpness of the vinegar and adds mild sweetness.
- Vinegar
- Adds acidity that sharpens the flavour and balances the sugar.
The step that matters
Add the dissolved flour and sugar to the cabbage. Flour lumps if added as dry powder, so it must be fully dissolved in the vinegar first. Stirring it in smoothly lets it thicken the liquid evenly rather than leaving clumps.
Swap the cabbage
How well each one fits the dish's main ingredients (onion, butter, vinegar, sugar, flour):
- Mustardfits better
- Shallotfits better
- Chivefits better
- Cabbagethe original
Fit is the average pairing score against onion, butter, vinegar, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
