When I was a student (in the dark ages) I used to work in a bakery in the holidays. One of my jobs was sausage rolls. We used to roll out a 12 foot strip of pastry, pipe the long 12 foot of sausage meat into it, roll it up and then cut it to size using a piece of wood for a template. Watching my mother make hers individually by hand, I (cocky dbrevil) ventured to tell her the "right" way to do them.
NOT a smart move. My ear was red for days!
