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 Tomato Pickle
Ingredients
Directions
Prepare the tomatoes
Slice the green tomatoes and layer them in a bowl, sprinkling a handful of coarse sea salt between each layer.
Let the tomatoes stand for 12 hours, then drain off the liquid.
Cook and store
Add the green peppers, sliced onions, vinegar, molasses, cloves, and whole mustard to the drained tomatoes.
Boil the mixture in the vinegar for 10 minutes.
Transfer the pickle into stone jars for storage.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the pickle, and salting draws out their liquid so they stay firm.
- Vinegar
- Provides acidity that preserves the pickle and sharpens its flavour.
- Molasses
- Adds dark sweetness that balances the sharpness of the vinegar.
- Onions
- Add savoury bulk and aroma as they cook in the vinegar mixture.
- Whole mustard
- Adds a pungent, tangy note that complements the sweetness.
The step that matters
Drain the salted tomatoes thoroughly. Salt draws water out of the tomatoes through osmosis. Removing that liquid before adding vinegar and sugars keeps the pickle from becoming watery and helps the pieces stay firm when simmered.
