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 ↓
Fresh Cucumber Pickles
Ingredients
Directions
Brine
Place small cucumbers of uniform size in a stone crock.
Pour boiling water over the cucumbers to cover them.
Add a large handful of coarse sea salt.
Let the cucumbers stand overnight.
Drain the water in the morning.
Pour more boiling water and the same quantity of salt over the cucumbers.
Let them stand until the next morning.
Finish and pack
Drain the water, wash the pickles in clear water, and dry with a towel.
Put the pickles back in the crock and pour boiling cider vinegar over them.
Add small horseradish roots to the crock.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small cucumbers
- Form the pickles themselves, becoming crisp and firm as they cure in the brine.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them, firming their texture during curing.
- Cider vinegar
- Adds acidity that gives the pickles their sour flavour and helps preserve them.
- Horseradish roots
- Adds a sharp, pungent aroma and flavour to the pickles.
The step that matters
Pouring the second batch of boiling water and salt. The second brine must match the first in salt amount and the cucumbers must stand fully covered. Under-salting or letting them float exposed lets the pickles soften or spoil before the vinegar is added.
