Ballotine of Foie Gras - chop or not?
I looked at five recipes, none of them called for the foie gras to be chopped.

You have already cleaned the liver, and have a different method chosen to form the ballotines, but I really liked these instructional photos from The Renaissance Girl Cooks describing the method from The Squire (a restaurant with two Michelin stars), and thought that later users might find them helpful.
