Why it works: Cucumber and horseradish match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 640 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mixed Pickles
Ingredients
Directions
Prepare the vegetables
Wash the tomatoes.
Cut a small piece from each end of the tomatoes.
Slice and chop the tomatoes finely.
Place the tomatoes in a wooden bowl.
Pare, quarter and remove the seeds from the cucumbers.
Cut the cucumbers into very small pieces.
Place the cucumbers in a jar with ½ pint of coarse sea salt.
Let the cucumbers stand overnight.
Peel the onions.
Cut the onions very thin.
Place the onions in a jar with 1 cup of coarse sea salt.
Let the onions stand overnight.
Brine and drain
Drain all vegetables thoroughly and place them in separate jars.
Cover each jar with cold weak vinegar.
Let the vegetables stand for 24 hours.
Drain the vegetables well, pressing hard to extract all juice.
Cook and combine
Place the tomatoes in a porcelain kettle and boil in good vinegar for 3 to 5 minutes.
Let the tomatoes cool, then drain and press out all juice again.
Mix the onions, tomatoes, cucumbers, 4 green peppers, and 1 cup of grated horseradish together.
In a pot, combine 2 quarts of best cider vinegar, 1 heaping pound of brown sugar, and 4 heaping tablespoons of mixed spices.
Bring the mixture to a boil and skim the surface.
Pour the hot mixture over the pickles and stir with a wooden or silver spoon.
Place the pickles in cans or gallon jars while hot and seal.
The pickles are ready for use in a day or two.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the pickle and, once salted and pressed, give a firm, chunky texture.
- Coarse sea salt
- Draws juice out of the vegetables through osmosis, firming them and reducing their water content.
- Cider vinegar
- Provides the acidity that preserves the pickles and gives them their sharp flavour.
- Brown sugar
- Balances the sharpness of the vinegar with sweetness and adds depth to the syrup.
- White onions
- Add pungency and bulk, softening in flavour as they are salted and pickled.
- Horseradish
- Adds a sharp, pungent heat that complements the vinegar and sugar.
The step that matters
Pressing out all juice after salting and after boiling. Excess liquid left in the vegetables dilutes the vinegar and sugar syrup, which can weaken the flavour and preservation, and makes the pickles watery.
