Why it works: Cucumber and mustard match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 2,281 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Chopped Pickles
Ingredients
Directions
Prepare the vegetables
Chop the green tomatoes, onions, mango peppers, and cucumbers separately.
Let them stand for several hours covered lightly with coarse sea salt.
Drain the vegetables and heat them in weak vinegar.
Make the pickling syrup
In a pot, combine the strong vinegar, sugar, mustard seeds, cloves, and ginger root.
Heat the mixture until the sugar dissolves, then pour it over the vegetables.
Bottle
Bottle the pickles for later use.

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 absorb the vinegar and sugar flavors.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Provides the acidity that preserves and sharpens the pickle.
- Onions
- Contribute savory bulk and a sharp, aromatic note once pickled.
- Cucumbers
- Add crunch and moisture to the finished pickle.
- Mustard seeds
- Add a pungent, sharp aroma that carries through the vinegar.
The step that matters
Salting the vegetables. Salting draws out water from the chopped vegetables, so they stay firmer and absorb less liquid in the pickle. Skipping or shortening the salting step can leave the pickle soft and watery.
Swap the onion
How well each one fits the dish's main ingredients (tomato, mango, pepper, cucumber, vinegar, sugar, mustard):
- Capsicumfits better
