Why it works: Vinegar and tarragon are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,547 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pickled Gerkins
Ingredients
Directions
Prepare and salt
Wash the gherkins and cut off their ends.
Place the gherkins in a cloth and mix with 4 handfuls of fine salt.
Shake the cloth and hang it in a cool place with a vessel underneath.
After 12 hours, add 2 more handfuls of salt and repeat after another 12 hours.
Pickle
The next day, place the gherkins in jugs and cover them with raw vinegar and spirits of wine.
Add spices and tarragon leaves.
Rest
Let the gherkins sit for 3 weeks before eating.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gherkins (in the method)
- Form the main body of the pickle, becoming firmer and crisper once salted and drained.
- Fine salt
- Draws out moisture from the gherkins, firming their texture and helping preserve them.
- Raw vinegar
- Adds acidity that sharpens flavour and helps preserve the gherkins in the jugs.
- Tarragon leaves
- Add a distinct herbal aroma to the pickled gherkins.
The step that matters
Salting and draining in the cloth. Salt draws water out of the gherkins over the first two days. Skimping on salt or skipping the repeat salting leaves more water inside, so the pickle turns soft and dilutes the brine.
