Slice your cucumbers into equally sized pieces about ¼” thick.
Fill a large mixing bowl halfway with ice, then add your cucumber and cover with cold water. Place the bowl in the fridge and let the cucumber sit in the ice bath for 1 to 2 hours.
In a pot over medium-high heat, add your vinegar, water, and all of the ingredients for your pickling spice. Bring to a rolling boil and stir until the salt and sugar are fully dissolved. Set aside to cool.
In a large mouth jar or container, add layers of fresh dill, peppercorns, garlic, and cucumber slices. Repeat the layering until you only have about a ½” of space left at the top.
Pour the cooled pickling liquid over the top of the cucumbers until completely covered. Add the lid to the jar and store in the fridge for at least 2 to 4 hours, but ideally 1 full day.
Serve alongside your favorite barbecue and keep in the fridge for up to 4 weeks.
