Mr. Rawles,
I recently discovered Pomonas Universal Pectin, for home canning. It stores indefinitely. It’s also very versatile: it makes regular, low-, or no-sugar jams, jellies, fruit spreads, gelatins, freezer jams, etc. (The other pectins I researched have about a 1-year shelf-life. It will work with sugar, artificial sugar, honey, stevia, or fruit juice as a sweetener. It will also gel things that don’t have any natural pectin, to make things like hot pepper jelly.
Their web site is PomonaPectin.com. It’s also available on Amazon. I’m not affiliated with them in any way. – Texas Sunflower
