Meta Description	These Peking Duck rillettes were actually the first idea that got me started on making the Peking Duck a four dish duck. Rillettes are a delicious potted spread made out of meat-a cousin to pate and terrines. Unlike pate which is made with liver, rillettes are made out of meat and are therefore more "accessible" to people that don't like offal. In this case I used the two legs of the Peking duck but you can also use duck confit legs or slow cook the duck legs yourself.
