I made that comment because in the article you linked they said the debated whether to troll readers by calling a hotdog a sandwich. Not surprised they wouldn't be trolling you. I never had such a cool grandmother as the one mentioned here .. https://www.bookcrossing.com/forum/5/131238/1495834 .
I'm not keen on jam either, but love the jam donuts the Vietnamese bakery up by the pub make.
