I think you should serve black Russians with borscht, blinis and caviar for Thanksgiving. Let's just attack this head on. Start serving nothing but Russian food daily. That's all he gets Russian food, more Russian food, and when he is full, more Russian food. He likes Russian, give him Russian until he barfs.
