I cured two separate pieces of pork belly. I used pink curing salt and measure it using a digital scale so I am pretty sure it was the correct amount. I put both pieces into vacuum sealer bags and vacuum sealed them to cure in. One piece sealed properly while the other bag had some salt stuck in the edge and did not seal. I resealed it so it was essentially a ziplock bag. When I took the belly out of the cure yesterday to smoke it I noticed the piece which had been vacuum sealed was bright red and the piece that was only ziplocked was a bit grayish, almost like oxidized beef. Should I be concerned? I will toss it out if you think it was not cured properly. Just seems strange since I used the same amount for both but the one looks a lot redder. Neither of them smell rancid.
Thanks for any help you provide,
