From the website:
This week it's a look at the golden age of Islamic food and conquest with guest Charles Perry, historian of Arab cuisine. Mr. Perry tells us that prior to 1400 A.D. there were more cookbooks written in Arabic than in the rest of the world's languages combined. And the seductive food in those old books is the stuff of dreams. Mr. Perry authored the foreword to Medieval Cuisine of the Islamic World: A Concise History with 174 Recipes.
A podcast of the program is available on the website.
