I haven't seen the UK version, and I have no idea where it's filmed. I watched the CBS version with Foxworthy, but that's the extent of what I've watched. And before hearing of this show, I had no idea who Mary Berry was, either.
My DD and SIL are foodies, and they live in England, but they've never mentioned the UK version to me. I'll have to ask them about it.
Enjoyed this episode. I know they are amateurs, and it's not like I could have done better, but some efforts did seem very amateur-ish. Still fun to watch, and I'm looking forward to seeing more episodes during this holiday seas
