Annoyingly, I love dark chocolate, but it's an incredibly effective migraine trigger (and for particularly nasty migraines, too - last time I had some of this, I managed to get lost a couple hundred yards from home.

Otherwise, I'm flexible. I love:

• G&B Maya Gold or Butterscotch
• Lindt Excellence Chilli
• Hotel Chocolat* Billionaire's Shortbread (and frankly, half the other things they do)
• Proper French profiteroles - filled with ice cream and covered in a thick, hot, dark chocolate sauce (which you save some bread to dip in too)
• The various chocolate spreads at Le Pain Quotidien
• M&S Belgian Chocolate Flapjack
• An obscure cardamom-flavoured chocolate that I've never found again

Next fix? There's some Waitrose Millionaire's Shortbread with my name on it at home...

* dangerous, as I have their outlet shop not too far from me...
