Here it is in action. It took a while to figure out just how much heat I needed to make it work properly. First it jiggled too fast, then too slow. I eventually got it just right.
Here's what I got done today. 4 Strawberry jams and 2 1/2 mushroom spaghetti sauces. I didnt know you werent supposed to only fill a jar 1/2 way if thats all you had. Oops. I guess I will have to use that soon. All of the jars popped close, but my jam did not set well. Its kind of runny :( Oh well I'm sure it will taste good on biscuits or on Ice cream.
