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
Wash and scrub cucumbers and red peppers.
Soak them in water for a few hours.
Drain.
Layer the crock
In a large crock, layer cucumbers, dill, mashed green grapes, chopped red pepper, and whole black pepper.
Repeat layers until the crock is nearly full, topping with plenty of dill.
Brine and ferment
Scald 2 cups of coarse sea salt in 7 quarts of water.
Cool the brine.
Pour the brine over cucumbers.
Ensure cucumbers are well covered; add more brine if necessary.
Cover with a cloth.
Place a plate with a stone on top to keep cucumbers submerged.
Let ferment in a warm place for 10 days.
Move to a cooler location.
Remove scum and wash the cloth three times a week.
Optionally, use 1 quart of vinegar for every 7 quarts of water instead of green grapes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the pickles and ferment into a crisp, tangy texture.
- Coarse sea salt
- Draws out water and creates the brine that keeps the cucumbers safe during fermentation.
- Dill
- Adds its aromatic, herbal flavour to the brine and cucumbers.
- Green grapes
- Mashed grapes add natural sugars that feed the fermentation, as an alternative to vinegar.
- Red peppers
- Add sweetness and colour to the layered crock.
The step that matters
Keep the cucumbers fully submerged under the brine. Cucumbers exposed to air can grow mold and spoil, while submersion keeps the fermentation anaerobic so lactic acid bacteria dominate and produce the characteristic sour flavour.
Swap the grape
How well each one fits the dish's main ingredients (cucumber, pepper, dill, vinegar):
- Limefits better
- Lemonfits better
- Avocadofits better
- Grapethe original
Fit is the average pairing score against cucumber, pepper, dill, vinegar. Candidates are from the same food group and used in at least 100 recipes.
