Pickling 101

In their book Home Made in the Kitchen (Viking Studio Books, 1995), Barry Bluestein and Kevin Morrissey simplify some basic pickling techniques:
FOR HOT SEALING: Submerge empty jars and flat metal seals in boiling water until ready to use. Fill and seal jars one by one.
FOR A HOT-WATER BATH: Place jars on a wire rack in the bottom of a tall 8-quart stockpot. Fill the pot with water to cover the jars by 2". Remove the jars, bring the water to a boil, and use tongs to lower the jars into the boiling water for the time the recipe specifies. Remove jars from pot and set aside to cool.





Also, though you do want to sterilize your jar lids, if you pop the flat metal seal part of the lid into boiling water and leave them there while you are making your pickles, they won't seal well at all, as being submersed in constantly boiling water for any amount of time will ruin the sealing stuff!
Here's another that I use: I keep the sterilized jars upside down on a cookie sheet in a 250 degree oven so that they remain hot and sterile until I am ready to add the ingredients.
