Historically, curing and smoking any meat was for preservation. In the cold Fall months, dad and some family and friends, slaughtered the 300 pound Pig they have been raising since early spring. The family, mom, dad, and 2 young children now have 250 pound of meat to eat and no cold storage. Rubbing down the pieces of meat with Salt, Sodium Nitrite and spices like Black Pepper, kept the flies off, and started pulling water out of the meat to stop bacteria from growing. The Nitrite Cure stopped the fat on the meat from going rancid and killed the deadly bacteria that causes Botulism. The Smoking added flavor, inhibited bacterial growth and stopped the meat from rotting while it was stored all year at room temperature, until the family could eat it. With the invention of refrigeration, especially freezing, curing and smoking has gone from a necessity to a choice because we love the flavor. Bacon can be rubbed with salt, sugar and cure#1, refrigerated for 2-3 weeks, then cold or warm smoked and you are good to go. This is Dry Cured Bacon. A second method is to place the same ingredients in Water and soak it for 2 weeks before smoking it. This is called Brine Cured Baon.
