This is the WoW Cookbook and yes, it is a real thing you can buy off Amazon:
It was published with Blizzard's blessing when MoP was current but had apparently been in development since Wrath. Mind you, real world ingredients were used with the recipes. Not everything made the cut as they had to strike a balance between stuff a novice could make and stuff that could be made without access to a restaurant-style kitchen. What made the cut also uses ingredients that can be sourced without too much detail and in some cases are modified with that in mind.
For example the Meaty Bat Wings Recipe uses Whole Chicken Wings and a dry rub so...yeah. The Forest Strider Drumsticks use Turkey Drumpsticks as well for another example.
Anywho, does anyone else have the cookbook?
