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 ↓
To Pickle Cucumbers
Ingredients
Directions
Prepare the cucumbers
Prepare cucumbers by placing them in the water they came from.
Cook cucumbers over low heat for 4–5 hours until they turn a pretty green.
Remove cucumbers and drain them on a fine sieve.
Once cool, add horseradish, mustard seeds, garlic, and peppercorns.
Slice additional cucumbers into small pieces and mix with the same ingredients until filled.
Sew the cut piece back on with a large needle and thread.
Make the pickle
Prepare the pickle by boiling vinegar with mace, cloves, ginger, long pepper, black pepper, Jamaica pepper, mustard seeds, garlic, and sliced horseradish for 5 minutes.
Pour the hot pickle over the cucumbers, seal them, and store for later use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- The main vegetable; gentle cooking softens them and turns them green.
- Vinegar
- Provides acidity that sharpens flavor and helps preserve the pickle.
- Garlic
- Adds pungent aroma and sharp savoury flavor.
- Horseradish
- Contributes a sharp, pungent heat that cuts through the vinegar.
- Mustard seeds
- Add a sharp, slightly bitter bite and aroma when steeped in the pickle.
- Black pepper
- Adds warm, sharp spice that rounds out the pickle's heat.
The step that matters
Cook the cucumbers over low heat. Gentle, low heat over several hours keeps the cucumbers firm and preserves their green colour. Higher heat breaks down their cell walls, making them soft and dull in colour.
