When researching my book, FEAST OF SORROW, one of the fun bits was trying out various ancient recipes. The book is about Apicius, a first century Roman whose name appears as the title of the oldest known cookbook. One of the recipes in Apicius is for Parthian chicken. Parthia was part of ancient Persia, now in a region of north-eastern Iran. Much to my delight, it turns out that the Parthians really knew how to make chicken. Hands down this is one of the best chicken dishes I've ever had. It's juicy and tender with a perfectly crispy crust. The original recipe calls for a spice called silphium (also called laser) which went extinct in the first century. Emperor Nero is rumored to have had the last sprig. Asafoetida powder or resin, common to Middle Eastern cooking, is believed to be the closest approximation to the taste. If you can't find that, just substitute garlic.
