You've never had a crumpet? You're missing out!
They're actually quite different than an English muffin. They're a lot less of a bread. Definitely moister. They're really hard to explain.
I don't know about there, but you can usually find them in the bread section in the grocery store. They're factory made and in sealed plastic, so you're getting a kind of crappy version, but still not bad. Just pop them in the toaster.
I don't know if it's still there, but when I lived in WA, I'd stop in at the crumpet shop on Pine (right by the main entrance to Pike Place Market) and buy fresh ones. Mmmmm
