Why it works: Allspice and ginger match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,620 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Green Tomato Pickle
Ingredients
Directions
Salt the tomatoes
Layer sliced green tomatoes and coarse sea salt in a pan, alternating with sliced onions. Let the mixture sit overnight.
The next morning, rinse and drain the tomatoes well.
Cook the pickles
In a kettle, combine the tomatoes with cider vinegar, brown sugar, mustard, allspice, ginger, cinnamon, cloves, black pepper, celery seed, sliced peppers, ground mace, and olive oil.
Boil the mixture for 3 to 4 hours.
If the vinegar is not strong enough, add cold vinegar while the pickles are still warm.

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 soften as they cook in the spiced vinegar.
- Coarse sea salt
- Draws water out of the tomatoes, firming them and reducing the liquid in the final pickle.
- Cider vinegar
- Provides the acidity that preserves the pickle and gives it its sharp tang.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Onions
- Add savory flavour and moisture that blends into the pickle as it cooks.
- Red or green peppers
- Add sweetness, colour and a little body to the pickle.
The step that matters
Boiling for 3 to 4 hours. Long simmering evaporates water and concentrates the vinegar and sugar, which is what keeps the pickle stable. Stopping early leaves it wet and less preserved, while overcooking turns the tomatoes mushy.
Swap the tomato
How well each one fits the dish's main ingredients (onion, cider, vinegar, sugar, mustard, allspice, ginger):
