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 ↓
To Pickle Red Cabbage
Ingredients
Directions
Prepare the cabbage
Remove the outer leaves from the cabbage and slice it very thin.
Sprinkle coarse sea salt over the cabbage and let it drain in a sieve for at least 12 hours.
Press or shake out the moisture from the cabbage.
Pickle and jar
Place the cabbage into clean stone jars.
Boil 1 ounce of black pepper in vinegar and cover the cabbage with this cold vinegar.
Alternatively, use strong unboiled vinegar, but it is not recommended.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red cabbage
- Provides the bulk of the pickle and its crisp, crunchy texture once salted and packed.
- Coarse sea salt
- Draws moisture out of the cabbage so it stays crisp and packs well in the vinegar.
- Vinegar
- Acidity preserves the cabbage and sets its sharp, tangy flavor.
- Black pepper
- Adds aromatic heat and spice to the vinegar brine.
The step that matters
Drain the salted cabbage thoroughly. Salt draws water out of the cabbage over many hours. If moisture is not pressed or shaken out before jarring, the cabbage dilutes the vinegar and can stay limp and soggy instead of crisp.
Swap the cabbage
How well each one fits the dish's main ingredients (vinegar, pepper):
- Capsicumfits better
- Mustardfits about as well
- Cabbagethe original
- Cucumberfits less well
Fit is the average pairing score against vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
