Thanks guys as usual for the great insight to the subject!
Tatoosh -- cool that you're in the Philippines! Been there once a number of years ago -- my wife is a Filipina -- I've been to Makati, Batangas and a handful of other places outside of just Manila..
Iam - Thanks for the background on the constitution of each mix and the interchangability (or lack thereof) info..
All: Thanks for the links & book recommendations -- I actually have the Charcuterie book on my Amazon wish list when I've got some spare $$
I'll keep you posted on my meat curing adventures!
