I'm pretty sure the cinnamon roll (or bun) is of swedish origin. You can find it all over the world, but according to wikipedia at least, it is from that beautiful country in the north. For those of you with not too much time on your hands, I would highly recommend the pre-made mix you can buy at IKEA (at least in the US), add some cardamom to the dough while baking, then before rolling the buns up, spread butter and sprinkle cinnamon and sugar on the flattened dough. Delicious. Especially with a nice glass of milk (you should definitely try that Andy). I made sure to bake some cinnamon buns last week and freeze them so I would have some for October 4th. It was awesome :)
As for self-checkout at IKEA, I've seen that at several IKEA's in the US (in Pittsburgh, Minnesota, and Chicago for sure). It is a pretty nice feature, but sometimes it can be problematic when people cant figure it out, or if the scanner machine doesnt work correctly. But it seems to be a theme all over the place in the US where they have self-checkout at grocery stores and home depot etc. as well.
I like this weeks JJ as well. Just so you know, the link in the shownotes for JJ's website doesnt link correctly.
