Stash the jar(s) of pickles in the fridge for up to 1 month—but we bet they won't last nearly that long. You can try them as soon as 6 hours if you're the impatient sort although the longer the pickles remain in the fridge, the more intense the flavor.☞ TESTER TIP: We found around 3 or 5 days to be the optimal waiting period before diving into your jar of pickles. By this time the dill will have mellowed, the sweetness remains noticeable, and the crunch remains pronounced.
