Chefkoch.de (means head-chef), has 109 recipes submitted by German speaking members that are about goulash with game. Not one of those I opened could be called traditional or even close. Most of them didn't even have paprika!

I'm looking at a Bigos recipe in a book, which says it's Poland's national dish, made from venison, chuck steak and pork, with (garlic flavoured pork and beef) kielbasa sausages, madeira, sauerkraut, tomatoes, dill seeds, dried mushrooms, (porcini mushrooms transform this dish into something that smells and tastes heavenly, if you can get them) and quite a few other ingredients.

What I suggest is, have a look at some of the US online recipe sites were Grandma from Poland explained to her new generation how to cook it. Then you'll get the recipe in English and it'll be traditional and authentic. The recipe I have here is true to type. It tastes best if made the day before.
