I read up on what a gammon is...
So, you want to cure this chunk of meat, maybe cold smoke it below 70 deg. F for hours or days to impart flavor, and NOT cook it until the slices hit the kitchen....
Chill the meat for 2 days to get it cold to the bone...
make up an injection brine/cure... 10% the weight of the meat using distilled water.... add kosher salt at 2% weight of the meat... add white sugar at 1% weight of the meat.... add cure #1 at 0.25% weight of the meat...
The ingredients are important... those ingredients are "clean" so bacterial growth will be retarded...
Brown sugar, non kosher salt have impurities that can impart bacterial growth and off flavors...
Cool liquid to refer temps... Inject the solution, ALL of it into the meat paying particular attention to the joints and along the bone... then inject the meat at 1.5" intervals to get complete coverage.. Refrigerate for at least 5-6 days... The gammon is now cured...
Warm to above ambient, form a pellicle, cold smoke below 70 deg. F...
Pellicle can be formed placing the meat on a wire rack in front of a fan for an hour or 2.. The meat surface will get sticky dry....
Cold smoking should be done over several days... 12 hours or so per day... the no smoke for 12-36 hours... the meat can remain in a "cool" smokehouse during the no smoke period... temps below 50 deg. F...
Cold smoke until you are satisfied with the color...
Keep refered during storage...
For a 10# gammon the ingredients would be..
1# distilled water.. 454 grams..
Salt... 91 grams..
sugar.. 45 grams...
cure #1.. 11.4 grams...
My choice for an injection syringe... You should make approx. 50 injections of about 10cc's each to get complete meat coverage at 1.5" intervals....
c farmer just used this method.. The ham after smoking and cooking to show how well this method cured the meat...
