I have a bit of a problem with wheat products (courtesy of a severely coeliac father), and particularly where fats are involved, on an empty stomach. So fried bread, croissants (and pizza...

) are generally 'right out'. Even bread / toast and butter can be an issue early doors. Obviously, the 'holy trinity' of an English, has to be eggs, bacon and sausage, but I have always seen beans and / or tomatoes as the standard addition. To me black pudding is very
nouveau, as is mushrooms. Hash-browns, pancakes, waffles and chips(!) very American, and very non-essential.
All well and good.
What I find pretty much unacceptable though, aren't so much the additions but what people pass-off as an English. Ham instead of bacon, frankfurter or chipolata style sausages, sausage meat patties and so on

. Naming no names, but several of the European owned establishments seem to be trading on a false premis, IMHO!

Had enough of the trolls. Going to sleep. I may be some time....
