Wait a minute! The book for sale on LuLu looks legitimate enough, but those comments? 100% enthusiastic, not a single doubt or reservation, and all written in very much the same style. Even gay RJers here have expressed some of the YUCK factor.
Plus what about the health issue? People wouldn't even use raw cows milk in a recipe in the US these days, everything needing to be Pasteurized and bacteria-free. Semen can contain some serious infectious agents, and must pass through the urethra, which can also be a source of disease.
Plus semen has many tastes; how do you cook with something that can taste different each time? Surely this is a hoax, and even if this is a real book (one review mentioned the "Choked Chicken" dish), it must be intended as a gag (pun intended), that you give to someone to watch them squirm and turn green.
"Nice dessert, Bill, but it coulda used a bit more of the jiz glaze."
"I know, Frank, but I was totally drained from making the peenie pasta. That Alfredo con Crema Personale sauce always takes a lot outta me. Maybe next time I'll ask you to help out in the kitchen, if ya don't mind."
"Yeah, I'd be glad to. I woulda brought some of my own supply from home, but I know how you insist on everything being fresh. Say, how 'bout I make us some Kahlua & Cream, to wash down dessert? Take me just two shakes in the kitchen."
"Great idea! I'll get the Kahlua while you make the cream."
Honestly, if there's any nutritional value in semen, I have a regular source in my healthy partner. And he's got this lovely built-in dispenser that's much more fun to milk for a direct treat, rather than going through all the delay & hassle of preparing a dish.
