Wash the cucumbers thoroughly under cool running water to remove any dirt. For the crispiest pickles, soak them in an ice water bath for 1–2 hours before fermenting, then drain well.
2 lbs pickling cucumbers
Trim about ⅛ inch from the blossom end (flowering end) of each cucumber. This helps remove natural enzymes that can cause pickles to soften during fermentation.
In a large, clean two-quart mason jar (or 2 32 oz mason jars), place all the whole spices into the bottom. Then add the dill and garlic. With clean hands, pack one layer of cucumbers tightly, standing on end, then add the bay leaves, then add the second layer of cucumbers standing on end. Or if using two 32 oz mason jars you'll only do one layer. Add the fermentation weight on top. Press everything down, leaving 1 ½ inches of headroom.
4-6 sprigs fresh dill, 5 garlic cloves, 1 tsp whole mustard seeds, 1/2 tsp whole black peppercorns, 2 dried bay leaves, 2 oak leaves or grape leaves
In a measuring cup or bowl, whisk together the filtered water and sea salt until the salt has completely dissolved. After experimenting with many different salt ratios, I prefer a 3% salt brine. This salt concentration creates the ideal environment for beneficial lactic acid bacteria to thrive while helping keep unwanted bacteria at bay, resulting in crisp, flavorful fermented pickles.
Pour the salt brine over the cucumbers until they're fully covered, leaving about 1 inch of headspace. Make sure to place a glass fermentation weight on top to keep everything submerged if you haven't already.
Cover the jar with an airlock lid or a regular lid left slightly loose to allow gases to escape. Place the jar in a cool spot out of direct sunlight (ideally 68–72°F) and ferment for 5–10 days. The brine will become cloudy and small bubbles may appear—both are normal signs of fermentation. Begin tasting the pickles around day 5. They'll have a light tang at first, while the sweet spot is usually 6–8 days, when the flavor is well-developed and the pickles are still wonderfully crisp. By day 9–10, they'll be tangier and slightly softer. I prefer a shorter ferment (around 5 days) as it results in a crispier pickle and slightly less tang. Once the pickles reach your preferred flavor, transfer the jar to the refrigerator to slow fermentation and preserve their crisp texture. Once the pickles reach your preferred level of tanginess, cover with an airtight lid and transfer them to the refrigerator or another cool place for cold storage. The flavor will continue to develop slowly while staying wonderfully crisp.
