Fill a medium pot 3/4 full with sunflower oil and heat to 360 degrees.
Lightly sprinkle working surface with flour.

Take your 4 inch cutter and cut out rounds.
Repeat with second half of dough.
Take excess dough reform into ball and cut more circles.
You should end up with about 20 dough rounds.

Wrap around the cannoli mold lengthwise.
Brush a small amount of egg white onto the edged that meet to seal them together.
Gently submerge each shell using a pair of tongs. (try to grip the edge of the mold and not the dough itself)

Once the shells are cooled, gently grip the mold with your fingers and slide the shells off.
