I just finished this one a few weeks ago. Very good read. He references the Tonkawas roasting the leg of a comanche over a fire. So they might've had a few "recipes".
I remember reading somewhere that once they were all on the Reservations in OK, The Comanches ended the few remaining Tonkawas. From the face of the earth. 😬
