Tips:
*The wild varieties of raspberries I use are slightly sour. If the raspberries are not so sour, the amount of sugar can be appropriately reduced.
*Adding a little glucose syrup can make the jam thick and reach the condensing point sooner, or not.
*The jam jar should be clean, it's best to boil it and sterilize it.
