I am always amused, though, when an eatery in one Country attempts to re-create a "traditional" dish from another. " Amused "sounds patronising but I sincerely don't mean it that way. It's just that food sometimes gets lost in translation in a similar manner to words.
The traditional english breakfast would never include hash browns but might, sometimes, have sauteed potatoes. More often than not, though, potatoes don't make it to the plate at all. I should add that the full English breakfast differs around the regions of the UK and nobody is ever going to truly tie down a "definitive " version.
Also In the UK we call blood sausage " Black Pudding" . This can be replaced with "white pudding" in some areas mainly in the North and Scotlandand has more oatmeal and less blood.
For a full English you would always get buttered toast with jam or marmalade ( croissants are French ) and a pot of tea ( not coffee ). Butterbeer doesn't exist outside of WWHP.
All in all I think that the people at The Three Broomsticks have done a pretty good job. I'm not sure if I'll try it because, like Scott, I'd rather have something different when on holiday.
I'm off to Scott Joseph's site to read more.................
To be honest I never have the full English at home but if we go away for the weekend then I enjoy it, but with fried eggs and fried bread or buttered toast for dipping in the eggs.
Eat too many of these those and you may be calling for the paramedics!
Correct me if I'm wrong, but isn't "egg in the basket" an English dish?
