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 ↓
Virginia Chow-chow
Ingredients
Directions
Prepare the vegetables

Add enough vinegar to cover the mixture.
Bring the mixture to a boil.
Transfer the hot chow-chow into airtight jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Adds bulk and a crisp texture that holds up through cooking.
- Green tomatoes
- Provide tart acidity and firm body, balancing the sweetness of the sugar.
- Onions
- Contribute savory depth and aroma as they soften in the vinegar.
- Brown sugar
- Adds sweetness that balances the vinegar and helps preserve the mixture.
- Vinegar
- Provides the acidity that preserves the chow-chow and gives it its sharp flavor.
- Coarse sea salt
- Draws water out of the vegetables, firming them and reducing excess liquid.
The step that matters
Drain the vegetables thoroughly. Salting draws out a lot of water. If the vegetables stay wet, the extra liquid dilutes the vinegar and sugar, weakening the preserving brine and making the chow-chow soggy.
