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.
Before use, wash jars in hot, soapy water and rinse thoroughly. Then put the clean jars on the wire rack inside the boiling-water canner. Fill with water and bring to a boil. Turn down the heat to keep the water below simmering. Keep the jars in the hot water until you fill them with pickles. If the recipe calls for presterilized jars, boil the jars completely submerged in water for 10 minutes before turning down the heat. In a separate small container, heat the lids (flat discs) in hot, but not boiling water.
