American bison are an important part of the prairie ecosystem and after a decline almost to extinction around the end of the 19th century, today there are many ranchers working hard to bring them back. I enjoy cooking and eating bison (sometimes referred to as buffalo).
The brands I've tried thus far have all been grass fed, lean, raised in a more sustainable manner and well, delicious. You may be able to find ground bison at your supermarket and it's pretty easy to use in recipes that call for ground beef. Bison steaks however are another story.
Because most bison is grass fed, it's leaner, like grass fed beef. Considered a highly nutrient dense food, it's lower in calories, fat and cholesterol than even chicken, it has 40% more protein than beef and is high in iron, omega 3 fatty acids and vitamin E. Without rich marbling, it needs more tender loving care. Wild Idea Buffalo recently sent me some samples of their products.
