pill. n. 1. (Pharmacology) a small spherical or ovoid mass of a medicinal substance, intended to be swallowed whole. 2. (Medicine) the pill (sometimes capital) an oral contraceptive. 3. something unpleasant that must be endured (esp in the phrase bitter pill to swallow). 4. a ball or disc. 5. a small ball of matted fibres that forms on the surface of a fabric through rubbing.
Fill your jars, while still hot place a waxed disc over the pickle, then a clear (cellophane) circle over the top of the jar, and secure with a rubber band. As anything with vinegar can get through the clear top it's best to put a metal lid as well, over the clear cover.
Quickly pour in the hot brine, remove air bubbles, add the lid and seal and insert immediately into your hot water bath. Once the required processing time has been reached, remove the jars from the water bath immediately. Over processing them will lead to cooked pickles, not crisp pickles.
