Piotr has written a quick-reference book on Polish holidays and had it published. The book describes the most popular Polish holidays and traditions in a conversational and witty tone. It also includes some of Piotr's own family traditions, giving the book a more personal feeling and making it easily relatable.
In addition to his own book, Piotr also co-authored and translated two Polish cookbooks which were published for the American market. He translated the books from Polish to English and contributed a few of his own recipes.
