Pasture-raised or grass-fed livestock and wild caught fish are rapidly gaining popularity at the supermarket. Aside from their superior flavor and more ethical treatment of animals, a growing body of research points to their increased nutritional content, compared to their industrial counterparts.
Simply put, bone broth is homemade stock made from animal bones such as fish heads or oxtails. You can use whole turkey or fish carcasses or parts of lamb, pig, venison – or any other animal of your choosing. The point is to simmer the bones (typically from one animal) in water for hours or days. The longer you cook it, the more nutritious it gets and the better the product breaks down and pulls out all the nutrients.
