As I said before, it's not the best recipe for brownies that I've ever made, but it's pretty good! This time, I used pistachio nuts left over from Easter baking, and chilli-flavoured chocolate (that was a bit of an emergency - my chocolate stocks were very low!)
here on the BBC Food website. I'd advise you to save a copy, as experience has taught me that the BBC doesn't keep celebrity chefs' recipes for ever! Next time you need it, it'll probably be gone! I find that 20 minutes baking leaves the brownies still slightly gooey in the centre, but I think my tin size is a little smaller than the one Nigella suggests, making the brownies a little deeper.
