Poutine — French fries generously slathered in gravy and cheese curds — is a classic Canadian treat that is said to have originated in Quebec in the 1950s. Since then, it has been adapted in many weird and wonderful ways from gourmet versions with lobster and foie gras to —believe it or not — a doughnut version. It's also inspired a crop of trendy "poutineries" and a "poutition" to make it Canada's official national dish.
