Good point about the Northeast, Mongo. I really know nothing about the cuisine of any of those areas. Point well taken about the arbitrariness of states, but that's really nothing new or unusual. All we need to do is look at the changes in national (let alone provincial, etc.) boundaries in Europe over the last 100 years. For changes in provincial boundaries, China is a good one, with a large area that was previously part of Tibet being awarded to Qinghai, for example.
