Most popular Palestinian dish is Kunnafa.
Synchs up with my experiences. My roommates in Italy used to make lots of polpetties and I would make a big batch of spaghetties al morbido to be helpful and try to pour it on top of the polpetteroes but they would try to stop me and push me away. Now I see where I was going wrong.
Ragų bolognese is very Italian but most regions have a typical ragu. "Alfredo sauce" is just based on pasta in bianco, which is like putting butter on toast something nobody goes crazy about but when some Americans tried it they went nuts over it and called it Alfredo then later added creme to it and the rest is history.
