If you're going to visit all those places, I suggest you start with Britain and Ireland. Germany and the Netherlands will be a bit more difficult, since not so many people understand English there... or well, at least not in Germany.
Oh... so jam is called "jelly" in Mickey Mouse Land? Lovely!
Beusenberry jam is awesome! ^^
