Plum my, iterate through and remove the bones. In the water, fill with sugar and bring to a boil, put back our plum. Cook 30 minutes until tender (if the fruit is well ripe, the time should be less). Let cool a bit and Porirua hand blender, if there is none - you can use the grinder (with it even better twist plum still raw). As for me, with the blender is less hassle :-). Again put the mass on the fire, bring to boil, reduce fire and ovarium until tender. It will take about an hour (but maybe more - it all depends on drain). Check: if you drop the jam on the saucer and after cooling it does not spread - all ready (there's a photo http://www.povarenok .ru/recipes/show/466 79/).

Output: 5 cans of 0.5 liters of Murphy's law got batteries at the most inopportune moment :- ( So took pictures of ready-made jam in the morning.
