Why it works: Horseradish and mustard 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 ↓
Chowchow Pickle
Ingredients
Directions
Prepare the vegetables
Chop the tomatoes, cucumbers, onions, and cabbage into small pieces.
Pack the chopped vegetables in salt and let them sit overnight.
Drain the salt and soak the vegetables in a mixture of vinegar and water for 1–2 days, then drain again.
Make the pickling liquor
Boil the spices in ½ gallon of vinegar with 3 pounds of brown sugar, then pour it over the vegetables while hot.
Repeat this process for 3 days.
Once cooled, mix 5 ounces of mustard with ½ pint of the best salad oil.
Add 2 quarts of vinegar to the mixture when it is cold.
Mature
Let the pickle mature for 2 months.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provides the bulk of the pickle and absorbs the vinegar and sugar liquor as it softens.
- Cabbage
- Adds crunch and bulk that holds its texture through long soaking in vinegar.
- Cucumbers
- Contributes crisp texture and body to the chopped vegetable mixture.
- Onions
- Adds sharp flavour that mellows during the long maturing period.
- White mustard seed
- Supplies pungent flavour that carries through the vinegar and sugar liquor.
- Brown sugar
- Balances the sharpness of the vinegar with sweetness and body.
The step that matters
Salting and draining the vegetables. Salt draws water out of the chopped vegetables by osmosis. Draining well before the vinegar soak keeps the pickle crisp and stops the liquor from being diluted.
