I used too much Instacure#2

[Jan Ooms]

Another couple of cents worth!!!!!!! Are you actually prepared to dry your Prosciutto for a long time. Prosciutto can be hung for up to 1 year or even longer, depending on conditions.
If you want to eat it in a few weeks time, I suggest that you toss it.
After 12 month drying your Prosciutto will be dried enough to be eaten as the cures will have worked their way out.
Have patience and you will be rewarded.
Hopefully somebody will chime in with more exact facts and figures.
Cheers,
Jan.
