I made a batch of Nigella's Choc and Pistachio Fudge last night - very yum! Am planning on giving some to a couple of friends tonight (early xmas pressie) and some to a family we're seeing on Boxing Day. Was thinking of putting the fudge for friends tonight in the fridge and the fudge for boxing day in the freezer - is this best? Both sets are in airtight containers. Also, would I have to defrost the frozen batch?
