This is easily one of my favorite "modern pasta" creations that I have ever whipped up. The flavor combinations are truly perfect. Decadently rich foie gras paired with incredibly soft confit duck for the filling and the tart sweetness of the spiced cherry-port reduction are completely magical. I like to top this pasta with a lightly poached egg yolk to create an even creamier sauce.
There really is no substitution for foie gras but if you can not find and give chicken livers a try in its place.
