Something may strike you as odd about the quantity; are there really 12 in that pack? The * refers to the small print in the bottom left corner. (Actually, it's really printed on the side of the packet, so you can't easily read it from above.) Here's a close-up:
In case you can't read that, it says: "* 12 mini rolls when halved". Now, in fairness, I can't really fault their logic on that. However, it would be equally true to say "24 mini rolls when quartered" etc. How many angels can dance on the head of a pin? This seems a bit like cheating to me, so it calls for a poll.
How many sausage rolls are in that pack?
Edit: Following up on stagknight's comment, please assume that the poll question said "mini sausage rolls". (I can't add a poll to an existing post - see FAQ.)
