dear welcome again, here in El salvador we do not have castor, only rabit and tacuacin(Didelphimorphia and some reptiles to eat, but your burger looks like nice, the meat of castor how it is, it is the same of rabit, it is strong or it is soft meat, it is the same of meat pork? but without grease i think?
I did not know that people eat castor meat, would be nice to tasted, and do you uses the skin of castor?.
Best regard and thanks for this interesting recype we usually eat boiled or in Grill this kind of animal that i say as rabit or tacuacin, this is hated by people because it eat their hen and chicken the tacuacin eat it.
Sorry for the late reply, @galberto. The meat of the castor is between pork and a turkey. No grease at all! The animals were brought to the USA for their fur, but I have never done anything with the fur. I think you would like the taste of this meat. Everyone who has tried my preparation of the animal has liked it -- but there are some people who will not even try it!
