Why it works: Tomato and cucumber are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 2,405 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
- Green tomatoes
- Provides bulk and a firm, tart texture once salted and pickled.
- Green cucumbers
- Adds crisp texture and mild flavor that holds up after salting.
- White onions
- Contributes sharpness and aroma that mellows during pickling.
- Green peppers
- Adds crunch and fresh, grassy flavor to the mixture.
- Celery seed
- Adds a warm, savory aroma typical of pickling spices.
- Pure cider vinegar
- Provides acidity that preserves the vegetables and gives them tang.
The step that matters
Squeeze the vegetables. Salting draws water out of the vegetables. Squeezing removes the remaining liquid so the vinegar is not diluted and the pickles stay crisp rather than soft.
Swap the onion
How well each one fits the dish's main ingredients (tomato, cucumber, pepper, celery, cider, vinegar):
- Capsicumfits better
- Mustardfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against tomato, cucumber, pepper, celery, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
