this seems to be far FAR too sweet, 800g of caster sugar is a lot and then 200g of marshmallow fluff? very sweet. Mine has yet to set, it's been in the fridge for 6 hours now. Also this makes far far more than a 20 x 30cm dish (unless you want 3 inch thick fudge) so I used 2 large cake tins, 1 of which is actually in the freezer and 2 hours on, STILL has not set. I'm hoping it will set by the morning. I'll come back and post what happens. - 18 Feb 2012
