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 Mixed Pickle
Ingredients
Directions
Prepare the vegetables
Slice the green tomatoes and large onions.
Cut the cabbage as for slaw.
Quarter the cucumbers lengthwise, then cut the cucumbers into 2‑inch pieces, leaving the peel on.
Add the small onions whole.
Mix everything with coarse sea salt thoroughly.
Let stand for 24 hours.
Drain off the juice.
Pour vinegar and water over the pickles.
Let stand for 1–2 days.
Strain again as dry as possible.
Spice and pickle
Mix the spices well, except for the ground mustard.
Boil 1½ gallons of fresh apple vinegar.
Pour the boiling vinegar over the pickles three mornings in succession, using the same vinegar each time.
On the third day, add 1 pound of sugar to the vinegar and boil.
Pour the boiling vinegar over the pickles as before.
Mix the salad oil and ground mustard with a small portion of the vinegar.
Add the mixture when cold.
Omit the oil if not preferred.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide bulk and a tart, firm texture once salted and drained.
- Cucumbers
- Supply crunch that holds up through repeated hot-vinegar pouring.
- White mustard seed
- Adds sharp, pungent flavour that mellows in the hot vinegar.
- Apple vinegar
- Acidic brine that preserves the vegetables and sets their tangy flavour.
- Sugar
- Balances the sharp acidity of the vinegar with sweetness.
- Salad oil
- Adds richness and carries the mustard flavour through the pickles.
The step that matters
Draining the salted vegetables. Salt draws water out of the vegetables. If they are not drained and pressed as dry as possible, the extra liquid dilutes the vinegar and the pickles can turn soft and spoil sooner.
