A question for pepperoni makers. Why is it that my pepperoni doesn’t get that nice smoky color on the sides that face each other when hanging over the sticks. It looks like it’s not done, yet the internal temp is 152. The sides that face each other are pale with no color. What is going on? I let the casings dry for a couple hours at room temp. They are properly spaced and not touching. Does the size of the dowel matter?
