I live out in China and I've recently started making and selling fresh British style sausages which people seem to really love (thank you to all the wonderful insight from members of this site).
Although I initially used natural casing I now only use collagen. I just find it less of a pain to use and as I make chicken sausages as well it's just easier having the one casing for all.
I sell the sausages in links of six and of course the links don't hold so when customers cut them they have the ends a bit flappy which I guess people are not used to. The sausages expand (often too much) during cooking so by the time they are cooked it is normally fine but it still doesn't help with people getting over the home made (look) versus professional looking.
Anyone have a good suggestion for dealing with this?
Also on the subject of the expansion I do still have trouble with splitting. I've been educating people on cooking (slow and low heat) and tweaking recipe which has helped but I still don't have it fully stable. I have interest from a couple of small local restaurants but I will have to fix this issue.
At the moment in my pork sausages I use about 80% meat (50%/50% shoulder and belly) 10% oats and 10% water. I used to use breadcrumbs and the problem seems better with oats. Could it be the collagen casing? I'm looking to try a different supplier but wonder if there could be much of a difference.
