How the hell did I overlook that. I'll try the next lot against a more comparable product - I've phoned a couple of labs, the cheapest's £35.10 plus vat for the tests. I've also asked my tame apothecary (pharmacist) but he hasn't the kit to do it - getting the things needed for the test method posted by Oddley isn't as easy as I thought and may even cost as much (but would do a lot more tests) - in any case I don't feel confident to do it accurately myself.
In conversations with NCPaul, I know that he would like to solve 'the riddle of the methods of calculation used by the FDA', and in due course he may make further enquiries/tests.
As far as I'm concerned this really isn't about the salt in this particular ham, answering only that would just be point scoring between two people who both have the same objective - to be able to calculate cures accurately and safely.
Of far greater benefit to us, and other amateur curers who take curing seriously, will be analysis of purely immersion cured meat that leads to us being able to predict outcomes for varying sizes of meat with confidence.
In another area, but related - I will do some trials to try and get a ball-park figure for the possible loss due to seepage in injected meat when using syringes/marination needles.
In due course I will get this recipe tested; not to prove a point, but to be confident that the cure is safe. It'll probably be when I do the next one - it won't be this one 'cos it's started snowing and I ain't going anywhere in this weather!
If any of you keep stats of weight etc before and after curing (or even during) for pumped or immersion cures (or even both combined) I'd be interested in having copies as I'm sure would other members who are interested in these technicalities.
