Making your own foie gras, from raw liver, will give you not only the satisfaction of having made it yourself, but also a liver of simply remarkable quality and taste, far better than any commercial foie gras.
It's a tricky operation, but one that's entirely within your grasp, as long as you follow the 3 delicate stages of the recipe, which are well explained here, in the following order: de-veining, seasoning and cooking.
This recipe will be cooked "en ballotine", a simpler and much easier method than the classic "en terrine".
