Don't have the chunks too big, they keep water trapped and the end result is watery needs more time to cook. I also use less sugar, 600g. Reduce a bit the lemon juice if you like it sweeter. Cook it until it gets dark red in color, for me the temperature never reached 220. The bottom of the pot may form caramelized sugar, don't scrap it off at the end, it is blackish and can be hard when eating.
