Investigator Ivan Oransky recommends—or rather, recommends being aware of — this book Natural Harvest — A Collection of Semen-Based Recipes, by Fotie Photenhauer.
The publisher (the book appears to be self-published) says:
“Semen is not only nutritious, but it also has a wonderful texture and amazing cooking properties. Like fine wine and cheeses, the taste of semen is complex and dynamic. Semen is inexpensive to produce and is commonly available in many, if not most, homes and restaurants. Despite all of these positive qualities, semen remains neglected as a food. This book hopes to change that. Once you overcome any initial hesitation, you will be surprised to learn how wonderful semen is in the kitchen. Semen is an exciting ingredient that can give every dish you make an interesting twist. If you are a passionate cook and are not afraid to experiment with new ingredients – you will love this cook book!”
