Some say peel the skin of.
Some say okay to eat the skin.
Some say it's made of plastic.
Some say it's made of paper.
Some say if it's got staples either end then peel it.
Some say it's made of the same stuff as UK sausages are made from.
Some say it's made of every part of the pig.
Some say shoulder of the pig.
I would say if you find it hard to eat with the skin on then that one has been made out of an old coke bottle, or left over miners boots.
Just hope it's not made of the same stuff, and in the same way as Sav's are made.
