Hello all. I am making a red wine (cooked) salami based on a recipe from Duncan Henry on youtube. The recipe calls for letting the salami sit in the fridge for anywhere up to a week. I let mine sit for 6 days and am about to start the smoking process. When i took it from the fridge, i noticed a white "film" on the casing (fibrous casing). I assume this is some sort of mold. i put it in the smoker anyway. is this white film a bad mold or ok mold?
