3Prepare canning jars and lids by washing in hot soapy water and rinsing in hot water. Place sheet pan in oven to set washed jars on. Turn oven on to bake at 250 degrees to get jars hot. Place large deep pot of water onto high heat, and bring to boil.
Make sure you have right canning tools to grab hot glass jars out of oven, and funnel. Get a small bowl of very hot tap water and soak seals and lids in it.
Grab a glass jar out of oven, place funnel in jar and start scooping out your cucumbers and liquid and fill jars. Fill just to 1/2 inch from top of jar making sure cucumbers are covered.Wipe top of jar off to make sure seals properly. Place seal and lid on and seal tight, immerse in boiling pot of water for 15 minutes.
4Note: any seals that do not seal right will have to be redone with new seals. After finished in boiling water place on thick towel to cool and finish setting. I hope you enjoy these like I do!
