You may be right, we just shrug a bit and are happy to fanny around with recipes. I just find it interesting as it is not like we are going to Bologna and telling them what “real” Bolognese is*, it is just our take on something vaguely Italian that we came up with post-war. As for calling lager real ale, plenty of weird and wonderful things get created called IPAs. If it was British people messing around with established recipes, or calling cheese slices “proper Stilton” or something, words could be said.
