I generally don't do sweet things and we don't have stuff like biscuits in the house, but I'm partial to the Annas pepparkakor – even if the self-serve warehouse didn't come up trumps (which it rarely did), you could sit in the Ikea car park scoffing a packet of biscuits and washing it down with some kind of lingonberry liquor, safe in the knowledge that you're still classier than 90% of Croydon.
That said, I bought all the flavours (almond, ginger, and orange) in a deli yesterday (along with two bottles of gin) and now I'm eating them all: they're ten times more addictive than crack. You probably need a licence and they're strictly rationed in Sweden and only sold in state-owned pepparkakor shops.
