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 ↓
Pickled Cabbage and Onions
Ingredients
Directions
Prepare the cabbage
Remove the outer leaves from the cabbage and cut it into quarters.
Remove the stalk and shred the quarters finely.
Lay the shredded cabbage on a dish and cover with coarse sea salt, then let it sit for 2-3 hours to draw out juices.
Squeeze the cabbage dry to remove excess salt.
Pickle the cabbage
Boil ½ pint of vinegar with 1 oz black pepper and 1 teaspoon sugar.
Place the cabbage in a jar and pour the cooled vinegar mixture over it.
Pickle the onions
For pickled onions, peel and wash 1 lb of small pickling onions in cold salt water.
Pack the onions in a jar and cover with 1 pint of vinegar and ¼ oz black pepper, adding a little ginger.
Seal the jar and store; the onions will keep for a year.

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 pickle and, once salted, becomes crisp and firm as it loses moisture.
- Vinegar
- Provides the sharp acidity that preserves and flavours both the cabbage and the onions.
- Small pickling onions
- Hold their texture in the vinegar and add mild, sharp onion flavour to the jar.
- Sugar
- Balances the sharpness of the vinegar with a touch of sweetness.
- Black pepper
- Adds warm, pungent spice that infuses into the vinegar.
The step that matters
Squeezing the cabbage dry after salting. Salt draws water out of the cabbage. Squeezing removes the excess salt and liquid, so the cabbage stays crisp and the vinegar is not diluted or overly salty.
