I cured two pork bellies, i have used prague powder #1 on both. Now when i cured both i used different rubs but both contained kosher salt and brown sugar. One of the bellies came out pink in the middle after i smoked it while the other looks more like a dark jerky color. Both were cured in the fridge for a week. I've read that after curing and smoking the pork should be pink in the middle like you see in grocery store bacon. Because my own belly is dark does that pose a risk?
