Fill a canner with a rack with enough water to cover the tops of the jars. Remember that when the canning jars are added, the water in the canner will rise. Add the canner lid and heat the water to a simmer.
Prepare pint or half-pint canning jars by washing and then placing them in an oven set to 350°F to sanitize. Drain the water off the jars, but do not dry them. Heat for at least 15 minutes. The heat will sterilize the jars and also prepare them for canning.
In a medium pan, add washed lids and rings, then fill with enough water to fully cover them. Heat and let simmer for 15 minutes. Do not boil.
Pour the crock syrup liquid into a large pot and heat to a boil.
Remove jars two at a time from the oven and pack with pickles. Use a spoon to help pack the pickles in. Using a funnel or a glass measuring cup with a spout, pour in enough boiling syrup to completely cover pickles, leaving a 1/2-inch air space at the top of the jar. Do not fill the jars to the top.
With a wet, clean cloth or paper towel, wipe the jar tops to remove any liquid. Using tongs, retrieve a lid and ring from the simmering water and place them on the jar. Tighten with a towel. Do not overtighten.
Repeat until all jars are filled. Then place the jars on the rack in the canner and simmer for 10 minutes.
Remove the processed jars from the canner and set them on a rack or towel, spacing them far enough apart to allow air to circulate so they will cool. Jars will self-seal as they cool. When sealed, the center will self-flatten and stay flattened if you press on it. Do not press on the lid centers before they seal.
Write the date and "Icicle Pickles" on the jar lids. They will last for a year or more.
