As I said in another post you can't get a decent banger here on OZ so I've started, with a friend, to make them myself. I just thought I'd chronicle my adventures so far to see if it elicits any new tips or helps out others.
Batch #1 Made with rump steak (won in a raffle) and pork belly. Seasoned with salt, pepper, rosemary nutmeg and lemon zest. Equipment used - George Foreman mincer with sausage attachment. Result - inedible. Fat does matter and we seriously underestimated the amount we should use. We were also a bit light on the seasoning so the taste was very muted. These were so dry that I wouldn't even feed them to the dog. The very dark colour (almost like bratwurst) was off putting as well. However, the experience was a good one as we worked our way around the technical difficulties especially the stuffing procedure. Learning to avoid splitting the casings while stuffing was a learning curve and we went through 15 metres for about 6 kgs of snags. In hindsight rump steak is not ideal for sausage making.
Batch #2 This time we got the local butcher to choose the proportions and contents for us. chuck steak, beef fat, pork shoulder and pork fat. The fat to meat ratio this time was easy to calculate and was about 25%+. We also used a little vege oil at the end. Seasoned with salt (more this time), ground white pepper (ditto), rosemary, oregano and nutmeg. Minced and seasoned the meat and then cooked a very small patty to check for taste. Added more seasoning and the glug of oil. Checked again and all seemed better. Stuffing was easier this time as we used our previous experiences as a guide. These actually look like sausages and they've been in the fridge for about 20 hours now. Can't wait to try them. If they are successful then we're on our way!
The whole thing has been a tremendous learning curve and one I'm thoroughly enjoying. I'll use a couple of mates to help me taste test the product. One in particular will be very blunt.
