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 ↓
Green Sour Pickles
Ingredients
Directions
Brine
In a stone jar, layer the sliced cucumbers or tomatoes with salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coarse sea salt
- Draws water out of the vegetables and seasons them during the overnight brine.
- Cucumbers or green tomatoes
- Form the main body of the pickles and absorb the brine and vinegar flavor.
- Vinegar
- Provides the sour acidity that defines the pickles and helps preserve them.
- Green or red peppers
- Add flavor and color to the pickles as they steep in the vinegar.
- Whole cloves
- Contribute warm, aromatic spice flavor to the pickling liquid.
The step that matters
Draining off the brine before scalding. Rinsing away the salty brine before scalding keeps the pickles from becoming overly salty, while the vegetables stay firm enough to hold their shape in the vinegar.
Swap the clove
How well each one fits the dish's main ingredients (cucumber, vinegar, pepper, horseradish):
- Dillfits better
- Tarragonfits better
- Capersfits better
- Clovethe original
Fit is the average pairing score against cucumber, vinegar, pepper, horseradish. Candidates are from the same food group and used in at least 100 recipes.
