I have a glass top electric cooktop.
(I miss my gas stove from 3 houses ago.)
I plan to can lots of thimble berry jam this year. Next year I hope to do tomatoes, too.
I was looking at the canners at the store and they come in a couple of sizes. Does the canner have to fit the element on my cooktop? I have the most annoying cooktop. It has 5 elements but only one of them is large and it isn't as large as an average stove.
Anything else I need?
Which kind of pectin do you buy for jam and why?
