I like the butchering idea, and when we've got cooks running around, why not be able to use the 'Finest [300/300q] Tefusang Steak' to REALLY knock someone's socks off when you make a 'Finest [300/300] Tefusang Grilled Meat' that like, kicks tooshie somewhere. Health/Endu gain when eaten?
Maybe when the NPCs start buying in relation to the quality of products, something like this would be the equivalent of platinum; something this good is reserved for the rich, ya know? Come in, cook at Brado's or Allelia's, make some awesome dishes, and sell them to the NPCs (or players who feel rich) so they can serve customers (or the Octarchs and Vigelesmi) high quality food.
Edit:
And then Tefusang Gibblets, or Tefusang Meat Scraps, maybe some of the major organs and other things (heart, liver, tongue). When you start off butchering, you can only do it once or twice on a carcass before you realize that it's now a ripped up mess. As you get better, you cut better, getting you 4 or 5 times at a carcass to get things.
Oh man, this is exciting.
Edit of the edit:
By the way, I don't like Tefusangs.
