In reading Michael Ruhlman's charcuterie book, he mixes and matches using Instacure, lactic acid culture and salt for various different recipes.
For a whole leg of ham, its just salt, whereas for brasaeola its instacure and salt and for salami its instacure, salt and culture, whereas for saussison sec its just instacure and salt.
confused?? Yes, me too!
The idea behind the culture is to inhibit the botulism bacteria from growing whilst in an anaerobic non-acidic environment as it produces lactic acid which the bacteria dont like, hence the salami, etc can dry out at the right temp without fear that the bacteria will produce their spores. But why not use this for saussison sec? Surely, its the same but only smaller (so it is the drying time??)
Equally, if brasaeola needs instacure, then why not a leg of ham?? Both a lumps of meat with no air pockets inside of the joint which could possibly have botulism spores in them, and i would have thought that raw beef is inherently safer than raw pork, even when cured!
So is this to manage just botulism or are there other nasties which need to be handled using different methods or are created by performing different processes, i.e. cold smoking??
