Why it works: Tomato and celery are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,377 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk and moisture that become the body of the pickle.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that preserves the pickle and gives it its tang.
- Onions
- Add savory flavor and aroma as they soften during cooking.
The step that matters
Bring to a boil and cook for 1.5 hours. A long, steady simmer lets the vegetables break down and the liquid reduce into a thick, spreadable pickle. Too little cooking leaves it watery and the vinegar sharp.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, celery, sugar, vinegar):
