I used the forum pre mixed pancetta cure with a small free range British pork loin, as I had it to hand. Not much fat on this one so I left it and the skin on. Cured in a vacuum bag for 7 days. Then rubbed in pepper and herbs and hung in our cellar for a good few weeks (5 or so) for just under 40% weight loss. No casing I just out it in a little tight mesh bag. Didn't touch it in that time, had a small amount of white mould when I took it out, so all good. Anyway, here is a pic. It tastes good too, fortunately.
May be I should try a leg!
