I've been making refrigerator pickles. It's super easy. For this jar I sliced 4 or 5 pickling cucumbers thin with my salad shooter along with some red onions (which later turned everything pink) and then added some red chili flakes and garlic. I put a tablespoon or two of pickling salt in the mason jar and added all the chopped vegetables. I poured in white vinegar till it covered everything, screwed on this lid, put in the frig, and in four days they were good to eat.
