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 ↓
Mother's Dill Pickles
Ingredients
Directions
Prepare the cucumbers
Examine cucumbers and discard any that are soft at the ends.
Soak cucumbers in water overnight.
Drain cucumbers on a clean board and dry with a clean towel.
Make the brine and pack the jar
Dissolve salt in enough cold water to cover cucumbers.
Optionally, add vinegar to the brine.
Layer dill, cucumbers, and whole peppers in a wooden pail or jar, repeating until all ingredients are used.
Cover with a clean white cloth, then place a plate and a stone on top to keep pickles submerged in brine.
Ferment and maintain
Allow pickles to ferment for 5-6 days if cucumbers are small and kept in a warm place.
Check pickles weekly, removing any scum and replacing the cloth.
If pickles are too salty, wash them and store in a weak saltwater solution with a dash of vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp body that is transformed into pickles during fermentation.
- Coarse sea salt
- Draws water out of the cucumbers and keeps harmful microbes in check while fermentation proceeds.
- Vinegar
- Adds acidity that sharpens the flavour of the brine.
- Dill
- Contributes the characteristic aromatic flavour of dill pickles.
The step that matters
Keeping pickles fully submerged in brine. Vegetables exposed to air can grow mould and spoil. A weight over a cloth keeps the cucumbers below the brine surface, where the salty, acidic conditions favour lactic acid fermentation over spoilage microbes.
Swap the cucumber
How well each one fits the dish's main ingredients (vinegar, dill, pepper):

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