Ok. Last week at Au Pied de Cochon, I saw several cans in their cooler labeled Duck in a Can. Later, as I enjoyed my lamb shank and later on, my sugar pie, I watched as a waiter picked up a can at the food station, slapped a "duck in a can" label onto it, and carried the can plus an opener (?) off to a table.
My question: what is in the can? How is it served? What is it served with?
Thank you for any insight.
By the way, dinner was great, lamb for me and pied de cochon for him, sugar pie, nice bottle of wine, three hours.
