I formulated this dish driving home from work one evening while trying to figure out how to shift gears from a weekend carnitas feast to a more elegant italian pasta night. I came up with the idea of showcasing the pork by crisping pieces of the leftover pork, and creating a reduction with shitake mushrooms and capers, drizzled over a nest of pasta on which the crispy-browned pieces of pork are perched. As you will see, the result was mighty fine!
Top with a small dollop of sour cream or cr?me fraiche 
Pull apart the pork butt into large shreds, similar to what you would use for pork barbeque.
