I only got into The Great British Bake-Off part way through, too. Somebody at work commented on it to me, after the 'European' episode where the technical challenge was making a Swedish prinsesstårta, asking me if I had seen it and if this was indeed a typical Swedish recipe. I hadn't, but it is, and I said so. This got me curious enough about the show to see if I could watch that episode on the BBC iPlayer, only to find that the episode was on again on the weekend. So I set my PVR to recorded it, and once I had watched it I was hooked!
