I have not used cure #2 as of yet The thought popped in my head just now...... how could I tell the difference between the two, they're both pink. What IF there was a "mistake" in the manufacturing and/or packaging chain and I end up with a pound of cure #2, labeled as cure #1. I realize the chances are very low of this happening but, you know what they say, STUFF happens. Somewhat relevant... Couple of years ago, my son, who does not live with me, came over to my house one day before I got home from work and made himself a cup of coffee. My mistake (won't happen again)..... I had a ziplock bag in the cupboard with leftover salt+cure #1 in it. He thought it was sugar........ "what kind of coffee did you buy??? that was the worst coffee I ever tasted!!". He only had one sip.
