Cranberry sauce
Cranberry sauce or cranberry jam is a sauce or relish made out of cranberries, commonly served as a condiment or a side dish with Thanksgiving dinner in North America and Christmas dinner in the United Kingdom and Canada. There are differences in flavor depending on the geography of where the sauce is made: in Europe it is generally slightly sour-tasting, while in North America it is typically more heavily sweetened. The recipe for cranberry sauce appears in the 1796 edition of American Cookery by Amelia Simmons, the first known cookbook authored by an American. In 1606, the Mi'kmaq people introduced the French settlers in Port Royal, Nova Scotia to Cranberries. They would have been sweetened with maple sugar and served at the settlers first Thanksgiving in North America that year. The settlers described eating what they called “small red apples" in letters send back to France. Port-Royal reports contained menus describing cranberries. They are still called “pommes de prés”, or meadow apples, today in Acadia.
