It isn’t hard and it isn’t difficult, it is just a pain in the ass! The work involved is rather boring but necessary. The first steps are injecting the bird and lifting the skin. I recall, while living in Paris, I used to hear about truffle under the skin, and I always asked myself, “how do they do it”… easy; the skin is elastic and can be lifted without tearing.
The truffles are placed under the skin and voila. But tonight I didn’t bother to stuff any truffles under the skin. I simply injected the bird and blanched it to render the fat. It is pretty easy and takes a little effort as you can see. Be careful the cavity collects hot water and can scald your hand. This is an exercise of patience.
