In Europe and America it is easy to find fresh fruits and berries, but here in Asia these are imported goods. You can find Mangoes, Papayas, Lychees and more, but I don't like these as jam.
The imported fruits are expensive and most often tasteless as they arrive unripe. I do not make jam with those, they do not taste at all.
Freezer jam is an easy way of making jam without using so much sugar. The fruits and berries taste much more, but this is not a jam you can keep for long.
1 kg frozen or fresh Raspberries
approx. 400 g Sugar
There are two kinds of Pectin, powder or liquid. I used Pomona's, please check the label on how much you need to use and how to prepare it! Mix it very well with the water, either by hand or even with the blender!
Now go and use your muscles and mash them with a potato masher. Mix the pectin as explained before and mix it into the berries. Go on mashing and mixing until the berries turn sticky and jam-like.
