Why it works: Cucumber and dill match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 530 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Dill Pickles
Ingredients
Directions
Prepare the cucumbers
Wash the cucumbers and cover them with cold water overnight.
Drain, wipe dry, and pack the cucumbers tightly in stone jars with fresh dill between layers.
Add 2 small red peppers, 1 teaspoon of peppercorns, 2 bay leaves, and 2 thin rounds of horseradish root to each half‑gallon jar.
Make the brine and seal
In a pot, combine 6 quarts of water, 1 pound of rock salt, and 1 teaspoon of alum; heat to boiling.
Add 1 quart of pure cider vinegar to the boiling mixture and pour it over the pickles, covering them well.
Seal the jars tightly while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the pickles themselves, firm and crisp when cured in brine.
- Rock salt
- Draws water out of the cucumbers and seasons the brine for a firm, preserved texture.
- Cider vinegar
- Adds acidity that lowers the pH and gives the pickles their sharp, tangy flavor.
- Fresh dill
- Contributes the characteristic herbal aroma of dill pickles.
The step that matters
Sealing the jars tightly while hot. Hot-packed jars that are sealed while the brine is still hot help drive air out and create a vacuum seal as they cool, which keeps the pickles from spoiling. Loose seals let air and microbes in.
Swap the horseradish
How well each one fits the dish's main ingredients (cucumber, dill, pepper, cider, vinegar):

Fit is the average pairing score against cucumber, dill, pepper, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
