We ran a Smokehouse for 7 years and this is one of our recipes:
1 haunch of roe(2.5) bone in.
1 box big enough for haunch
1 black bin liner
5kg salt
1 tin black treacle
and fresh roesmary.
Put bin liner in box and put a layer of salt (about 1") in the bottom of the bin liner.
Use a filleting knife and insert it down the bone so you can get some salt down there, otherwise you can get the bone taint,(the meat cures but the bone goes off before the salt gets to it).
Coat haunch in the treacle and the herbs( the sugar in the treacle/molasses stop you getting a hard crust, as well as adding sweetness), place in box and cover with salt completely,tie up the bin liner so no nasties can get into it.
After 1 month take out the haunch and wash it and dry it.
Cover in a fine Muslin cloth and leave for 6 months,if a mould appears which is normal then you can if you wish just dunk it in a weak vinegar solution which will kill the mould..
This recipe produces a parma-ham style meat..
PS: if you wish to speed up the process then dry the ham in a condensing chill, usually takes about 20 days..
Word of warning,remove as much fat as possible it turns rancid when cured..
