This jam could be frozen too, just leave ½ inch of head space for expansion.
Use as much sugar or less you want, because it depends on how sugary the fruits are.
Fruit varies in water content as well, and some fruits may take longer to jam up. Pay attention to to the bubble size, sheeting, and use the spoon test!
REMEMBER- Home made jam is of thinner consistency because we do not add any pectin. If you do like thick set jam, then add some pectin to it.
Additions: Your can add any spice you want, you can omit the cocoa and cardamom.
