Why it works: Clove and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Tomato Pickle
Ingredients
Directions
Prepare the vegetables
Sprinkle sliced tomatoes and onions with coarse sea salt and let stand overnight.
Drain the vegetables.
Make the pickles
In a kettle, layer spices and the drained tomatoes and onions alternately.
Wet the mustard before adding it to the kettle.
Cover the mixture with vinegar.
Boil for 10 to 15 minutes.
If the pickles taste too sharp, add sugar to balance the flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomato
- Provides the bulk of the pickle and its tart, firm texture once salted and cooked.
- Onions
- Add sweetness and body that softens during the long cooking.
- Vinegar
- Provides the acidity that preserves the mixture and gives the pickle its sharp flavor.
- Mustard seed
- Adds pungent, sharp heat that blooms in the hot vinegar.
The step that matters
Drain the vegetables after salting. Salt draws water out of the tomatoes and onions overnight. Draining removes that liquid so the pickle stays firm and the vinegar is not diluted.
Swap the tomato
How well each one fits the dish's main ingredients (onion, pepper, clove, mustard, allspice, vinegar, sugar):
- Horseradishfits better
- Shallotfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against onion, pepper, clove, mustard, allspice, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
