Pierogi with Prunes, Orange, and Walnuts

To be honest, pierogi with prunes weren’t my favorite growing up. My grandma used to make these every Christmas Eve, mostly to spoil my uncle, who can easily eat a dozen of them. She puts a beautiful whole dried plum in a piece of dough and cooks it, but I prefer to blend the prunes to a smooth paste flavored with orange and cinnamon. Chopped walnuts add a pleasant contrast to these soft dumplings.
