It is certain that food is the number one (or maybe number two) cause for deadly wars and bitter disputes. I am not talking about the obvious fights over resources or price peaks, but about the ownership of recipes.
Who owns mousaka, Greece or Turkey? Or hummus, Lebanon or Israel? Or canard a' l'orange, Italy or France (actually I know the answer to this one...)? Book and books will tell you one or the other story. Depending on the preference.
