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 ↓
Old Virginia Mixed Pickle
Ingredients
Directions
Prepare the vegetables
Slice the green tomatoes and large white onions.
Cut the cabbage as for slaw.
Cut the cucumbers into quarters if small.
Mix the vegetables in a jar, adding salt as you go.

Drain off the water that rises.
Wash the pickles with clear water.
Add the small whole onions that have been soaking in salt water for 24 hours.
Press and season
Pour equal parts water and vinegar over the pickles.
Let them stand for a day or two.
Place the pickles in a cotton bag.
Press until no water can be extracted.
Mix the spices with the pickles.
Scald and pack
Boil 1½ gallons of fresh apple vinegar.
Pour the hot vinegar over the pickles.
Repeat this process for three mornings, using the same vinegar each time.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk of the pickle and absorb the brine's flavour as they stand.
- Cucumbers
- Add crisp texture that holds up through the salting and pressing.
- White onions
- Contribute pungency and sweetness that mellows during long brining.
- Cabbage
- Adds crunchy bulk that stays firm through the salt curing.
- Apple vinegar
- Provides the acidity that preserves the pickles and sharpens their flavour.
- Sugar
- Balances the sharp acidity of the vinegar with sweetness.
The step that matters
Pressing out the water. Salted vegetables release water that dilutes the brine and leaves the pickle soft. Pressing until no more liquid comes out keeps the pickles crisp and the vinegar strong enough to preserve them.
