This is a very interesting topic because it relaits to Americans having a different culture than the rest of the world. I always get abuse when I say Americans have a difeerent culture. What do you expect? They have the same culture as an eskimo in Siberia? Or a Buddist in Mongolia?
American do treat the (humble) hamburger as most un-humble. Not only is it a national dish its a national dish one cant fu!!ck with!
the hamburger meat pattie will not be just beef but will have additives like onion, tobasco, herbs and spics, carrot and more. More and more, till we call it a "Rissole". But a USA hamburger pattie will only have, and I mean ONLY have beef. No flavorings, no binders,like egg yolk etc, just 100% beef and nothing else at all.
McDolnalds have a major problem in Australia
where they have to keep,advertising their beef patties as being beef and nothing else. Because eveyone expects the beef to have onion, carrot etc as well. Even mcdonalds cant understand the cultural difference. ONLY America has beef patties made of beef. ALL beef, nothing else.
So heres the bind, and i think someone else mentioned this, that if your meat patty is JUST beef is needs to be F'ing great beef or it tastes like sh!t!
In my 9 month ramble through the USA last year i found there is a Hamburger on EVERY restaurant menu, even if you are paying $1,000 per head
in New York
they will still have a hamburger. I never found a restaurant with a burger over $13 or $14 even when every other main dish was much more. Maybe its like the French subsiding the price
So the USA cooks must know what is acceptable and only sell that. The rest of the world does not know, and can not understand.... Its a cultural diffference.
So when in the USA go buy a Burger, and get to know and enjoy its unique 'burgerness' but never, ever, expect one like that out side the USA. Their aint one in paradise.
