sausage stuffer question

Kubbe is a traditional Middle Eastern dish comprised of a cylinder-like shell made from meat, usually lamb and bulghur wheat, the centre is then stuffed with a spiced minced lamb filling and the ends are sealed to form a parcel. These are then deep-fried. To make the outer shell requires great expertise; the Kubbe attachment should shape the outer shell ready for stuffing.

 

Larry, I believe the white middle disk is a Kubbe attachment.

 

Hey that is a picture of my grinder!

 

Looks like a bagel attachment
