I have just made some Chocolate Pistachio fudge from the 'Nigella Express' cookbook to take to some friends for dinner tonight. It is so easy (so easy that you kind of hope nobody asks you for the recipe!) and it tastes amazing. My husband came into the kitchen just to check i had saved him some to eat at home. I like the way that when you cut the fudge up you get to see the striking colour of the green pistachio nuts next to the dark rich chocolate.
