Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Green Tomato Pickle
Ingredients
Directions
Prepare the vegetables
Chop the green tomatoes, cucumbers, and onions very fine.
Salt the chopped ingredients well and let them hang out in the air overnight to drain juice.
Make the pickle
The next morning, place the chopped ingredients in a kettle and cover with cider vinegar.
Bring to a boil, then put into jars.
In the fall, chop the celery very fine and add it to the mixture.
Add the spices: cinnamon, mustard seeds, and red pepper to taste.
For each pint of the mixture, add 1 pint of sugar and boil together before putting in jars.

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 contribute tartness and body once cooked.
- Cucumbers
- Add crisp texture and moisture that releases juice when salted.
- Onions
- Add savory depth and aroma to the chopped vegetable base.
- Sugar
- Sweetens the pickle and balances the sharpness of the vinegar.
- Cider vinegar
- Provides acidity that preserves the pickle and gives it its tang.
- White mustard seeds
- Contribute pungent, sharp flavor that mellows during boiling.
The step that matters
Salting and draining overnight. Salt draws water out of the chopped vegetables through osmosis. Draining them well before cooking keeps the pickle from becoming watery and diluting the vinegar and sugar.
Swap the cinnamon
How well each one fits the dish's main ingredients (tomato, cucumber, onion, cider, vinegar, celery, mustard):
- Tarragonfits better
- Garlicfits better
