This plum and ginger jam is easier than most because it doesn't use pectin, you don't need to peel the plums, and with this small-batch method you don't need to devote your entire weekend to making it!
This recipe yields approximately 1250 millilitres (5 cups) of jam. Depending on the size of jars you are using, you will either get 5 small or 3 medium-large sized jars.
You will most likely have a small amount of jam left that doesn't fit into one of your jars. Just pour it into a small container or partially fill another jar and keep it in the fridge. You'll use that one first.
