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! ^^
