Picnics were both about 10#'s ,,, sooo, at ~4600 grams per ham I used about 500 grams (10%) each... Added the sugar, salt, cure etc. at the rate specified for the weight of the meat... Did not take into account of the liquid... reason being the added liquid will probably evaporate or cook out... What doesn't cook out will not have an adverse effect on the curing or the salt flavor... All of it will, or should, be left inside the meat.. It's a really quick curing method that takes up no extra room and reduces the time to cure... Adding spices or using stock kicks up the flavor a bit...
Each ham has it's own 500 gram container for liquid, spices, salt, sugar and cure #1... that is the only way I can insure the proper amounts of stuff get into each ham....
