Goodness knows why it didn't work - it was Delia's buttered brazils recipe and I've never had a problem with any of her recipes before.
Sadly, the toffee stuff went really horrid and grainy and hard and I wasn't able to roll the brazils in th mixture. Now I have to fill the space they would have taken up in the chocolate boxes and have loads of brazils left over.
It would be good if it was more interesting than covering them with chocolate - wandered if anyone had any ideas/recipes for me?
