the lobe on the work
surface with the smooth side up. Cut a narrow, 3/16" to 3/8", band from the long, narrow edge of the liver
and set aside. Turn the lobe over so the smooth side is down. Starting with the exposed major duct, at the point where this lobe was joined to the other lobe, use the backside of a paring knife to gently push the liver
away from the duct, all
the time keeping the blade against the duct. In this manner the whole duct network can be exposed in a single layer. Using the side of the blade, or a finger, gently pull the entire duct from the liver
and discard. In the same manner, remove the second duct network lying slightly deeper in the lobe than the first.
