carp and goose both go back on religious tradition. traditionally there would only be modest food on christmas day - to remember the conditions in which ol jesus supposedly was born. in my region, saxony, that is potato salad and sausages. regional tradition requires every wife to have her own recipe for this and be convinced it is the best one on the planet. only on christmas day 1 and 2 the more lavish food comes out. like my roast beef. or a goose. carp is for catholics. not many around here.
