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.
