Combine Seasonings. In each pint jar, place 1 smashed garlic clove, 1 tsp. peppercorns, 1/8 tsp. red pepper flakes, and 2 fronds of dill.
Prepare your cucumbers by slicing them into your desired shape--whole mini cucumbers, pickle spears, pickle chips, or crinkle cut pickle chips.
Divide the prepared cucumbers among the pint jars. Pack them close together, but not so tightly that they're full to bursting. If you have it, place one more frond of dill on top of the cucumbers.
Prepare the pickle brine by stirring together warm water, vinegar and salt until the salt is completely dissolved. Carefully pour the vinegar mixture into each jar, filling to cover the cucumbers, if possible.
Refrigerate the pickles. Secure lid on each pickle jar and refrigerate 24-48 hours before enjoying. (They'll continue to develop flavor the longer they sit in the brine.) Pickles should remain fresh 3-4 weeks in the refrigerator. They are not safe for long-term storage at room temperature.
