Why it works: Mustard and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Rough and Ready Pickle
Ingredients
Directions
Prepare the vegetables
Slice the cucumbers, green tomatoes, bull-nose peppers, and silverskin onions.
Salt each ingredient separately, then let them stand overnight.
Press them dry the next morning.
Make the pickle
Mix them together, chopping the onions and peppers finely.
Add black pepper, allspice, white mustard seed, celery seed, horseradish, and cloves.
Cover the mixture with vinegar and bring it to a boil.
For every gallon of the mixture, add ½ pound of brown sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the bulk of the pickle and give it a crisp, fresh texture once salted and pressed.
- Green tomatoes
- Add firm body and tart acidity that balances the sweetness of the sugar.
- Silverskin onions
- Contribute pungency and savory flavor that mellows during the long pickling.
- Brown sugar
- Adds sweetness that rounds out the sharpness of the vinegar and spices.
- White mustard seed
- Provides sharp, pungent flavor that mellows in the vinegar brine.
- Vinegar
- Acts as the preserving liquid, adding sourness that gives the pickle its tang.
The step that matters
Salting and pressing the vegetables. Salt draws water out of the cucumbers, tomatoes, peppers and onions. Pressing them dry before adding vinegar keeps the finished pickle crisp and stops the brine from being watered down.
