Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Sweet Green Tomato Pickle
Ingredients
Directions
Prepare the tomatoes
Sprinkle salt over the sliced green tomatoes and let them stand for 12 hours.
Drain off the water, then add the sliced green peppers and onions to the tomatoes.
Cook and store
In a pot, heat the cider vinegar, molasses, mustard seed, cloves, and allspice until it boils.
Add the tomatoes, onions, and peppers to the boiling mixture and boil for 10 minutes.
Pour the mixture into a stone jar and let it stand for 2 weeks before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk of the pickle and, after salting, a firm texture that holds up to boiling.
- Cider vinegar
- Supplies the acidity that preserves the pickle and gives it a sharp tang.
- Molasses
- Adds dark sweetness that balances the sharpness of the vinegar.
- White mustard seed
- Contributes a mild, pungent spice flavour to the brine.
- Onions
- Add savoury flavour and sweetness as they soften in the hot brine.
The step that matters
Salting and draining the tomatoes. Salt draws water out of the sliced tomatoes by osmosis. Draining that liquid before cooking keeps the brine from being watered down and helps the pieces stay firmer rather than turning mushy.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, cider, vinegar, molasses, mustard, clove):
