Yeah I know it's a harvest festival, but there are different foods grown in different places. If seal fins don't sound good, Samuel de Champlain used to have Thanksgiving festivals in New France (the part which became Nova Scotia), where the climate, time of year (& First-Nations cuisine) would have likely been different than it would have been in Massachussets. In Canada (according to wiki again) we only started to eat the usual turkey (etc) when the Loyalists moved north after the American Revolution, bringing the American Thanksgiving cuisine with them. I read that they grew lots of grains but I have a feeling that lobster & other seafood might also be more traditional Canadian (pre-American-revolution) Thanksgiving foods.
The bird could eat its way out of the cage. That was very real to me. As an apprentice, I too felt like a bird in a cage made out of bread. I just fed on my limits. -- Lionel Poilane
