I have been canning for years and use a big pot as I don't have a canner or pressure. Sure Jell has a no sugar needed pectin. I would use that so that your jam comes out perfect. Make sure the label says less/no sugar sure jell it is in a pink box. If you can't find it in the store amazon.com sells it but you have to buy something like 6 or 8 boxes. The regular sugar added Sure Jell is in a yellwo box.
