Method Of Preparation
In a pressure cooker add washed strawberry, blueberry, blackberry and little water. Let two whistles come.
Let the pressure settle and open the cooker. ,Mash well with the back of ladle and add sugar to it.
Stir occasionally till it becomes thick.
When it becomes thick, add lemon juice and stir frequently.
Switch off the flame when you get the jam consistency. (To check the consistency, take the cold saucer out of the freezer, put a little jam on it, and put it back in to cool for a minute. If it wrinkles when you push it with your finger, then it's done.)
When cooled store in air tight container.
Delicious jam is ready.
