3.5% salt for Kirby Cucumber

About Kirby Cucumber

Kirby (aka pickling) cucumbers are bred for fermentation: small (4-6 inches), thick-walled, low seed count, no wax coating. Grocery-store English or slicing cucumbers fail because their wax blocks brine penetration and their thin skin softens to mush.

Technique

Use brine-pickling method, not dry-salt. Cover cucumbers completely with 3.5% brine (35g salt per liter water). Weigh down to keep submerged. 3-5 days at 68-72°F for half-sour (still crunchy, mildly tangy), 10-14 days for full-sour. Add 1 dill head + 2 cloves garlic per quart for classic flavor. Grape or oak leaf adds tannin for crunch.

Salt level notes at 3.5%

Kimchi salting is a 2-stage process: 3.5-4% dry salt → 2-4 hour rest (flip halfway) → 3x rinse → paste application. The salt drawn into the water during rest is what rinses away. Final kimchi effective salt is ~2%.

Safety: Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.
