So very important !
The picture to the left shows you a jar with the ring/twist on and with the ring/twist off.
I am going to tell you a few things I personally noticed when this is NOT done.
First and most important when you give any of your preserve's as a gift or for sale you "must" have removed the twist. Let the person know once they open the jar they can replace it. If you do not feel comfortable just tell them or add a small note to the jar.
I have gotten jar's with the twist on that had a chip of glass because the rim of the jar was knocked during travels/storage. This chipped small piece of the glass once the jar is opened could easily be released into the ingredients.
Second is that there could be some of the ingredients that stayed on the rim and the twist not removed keep it there and it spoiled.
Bacteria my friends not good!
Always once your jar's have completely cooled remove the ring/twist from the jars and rinse the jars in warm soapy water to clean anything that may have been in the water-bath. Dry and store without the rim/twist.
Plus you will always have available rim/twist
