I'm thinking of purchasing some of these canning jars I heard about on this post. They would look so pretty in with my food storage. Have any of you ever used any canning jars similar to the Weck Canning jars? Are there pluses and minuses to using them versus using traditional American canning jars? Any comments would be nice. Just for your pleasure, the second picture I found on a food blog and have to share the recipe. It looks so tasty and easy.
