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 ↓
Cabbage Pickle
Ingredients
Directions
Prepare the cabbage
Quarter the cabbage and split each quarter.
Place the cabbage pieces in a wooden tray and sprinkle with coarse sea salt.
Let the cabbage sit for 24 hours, then drain off the salt.
Pack and seal
Pack the drained cabbage into a jar, layering with sugar, chopped onion, and spices.
Boil the vinegar until hot and pour it over the cabbage to cover.
Seal the jar tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the crisp, sturdy body of the pickle that holds its texture in brine.
- Coarse sea salt
- Draws water out of the cabbage, softening it and concentrating its flavor before packing.
- Sugar
- Balances the sharp acidity of the vinegar with a touch of sweetness.
- Onion
- Adds savory depth and aroma that mellows during pickling.
- Vinegar
- Acidifies the cabbage, preserving it and giving the pickle its tang.
The step that matters
Draining off the salt after 24 hours. Salt draws water out of the cabbage through osmosis. If the salt is not rinsed or drained off well, the pickle will be overly salty, and too little draining leaves excess moisture that dilutes the vinegar brine.
Swap the onion
How well each one fits the dish's main ingredients (cabbage, sugar, vinegar):
- Mustardfits better
- Radishfits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against cabbage, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
