• Substitute for Bourbon Biscuits

  Hello, I live in Geneva, Switzerland and some of the ingredients are really hard to find here. I am planning to make Nigella's Ice Cream Cake with Butter Scotch Syrup (Nigella Express p222) but can not find Bourbon Biscuits anywhere. Could you please tell me a substitute for them? Many thanks!! Aamna Ajmal

• Guinness

  I have all your cook books. The only thing that confuses is your being in the UK. I do not know what Guinness is. I do not know Marmite or vegmite is. I have never seen or tasted a Quince in the United States. So please tell me, what is Guinness? As far as I know, the other stuff I mentioned are not sold or known in the U.S.
