made jam last year had to use 3 large saucepans but this year it was so easy with this 9 l pan i cooked my plums in 1 go. from 6kg of fruit i made 12x 250ml jars. i didnt use the jars in the set as they were bigger than i wanted but there was everything in the box you might need. i used the thermometer which clipped to the pan and the funnel which made getting the hot jam into the hot jar easier. when cooled there were labels for the jars. I used it on my ceramic hob.
