I am relatively new here myself and not a kitchen wiz, and unfortunately time has taken me far from my German roots but a family recipe for saurbraten is what I'll start with. I haven't heard of any German/Continental European shops either. I am sure the kraut can be bought at Carrefour, etc.

Good luck with the move. . .get ready for the heat, if you have not been here before. This'll be my 'baptism by fire' this summer.
