Apricot Jam

According to Waitrose http://www.waitrose.com/recipe/Apricot_Jam.aspx Ordinary Granulated sugar is OK

Thanks Alan for that, like the recipe as no water or lemon juice, just sugar and apricots....Also like the idea of prepering then having a long rest before the cooking as the thought of jam making in this heat doesn't appeal.  Never turned jars upside down before either but it all makes perfect sense.

Apricots are high in pectin so the jam should set just fine without jam sugar. I do add a bit of lemon juice, though.  Also, if you put thye kernels in it adds to the pectin content - you can put them in a muslin bag.
