Paul Kovi's Transylvanian Cuisine: History, gastronomy, legend, and lore from Middle Europe's most remarkable region (HC, 1985, $3)
Paul Kovi is a co-owner of the Four Seasons restaurant in NYC. He is, though, originally from Transylvania. Another chef has written, "Hungarian-Transylvanians are the most colorful and gastronomically interesting group. Even though they share the same ideas about cooking as the rest of Hungary, because of their special historical geographical advantages they have developed and kept a remarkable culinary entity. To my mind, it's the most interesting part of the Hungarian kitchen."
