I use cold smoking to flavor things. Most times things that will be cooked or have been cooked or will be canned or dry cured. Hot smoking cooks and flavors. You need to be careful with cold smoking because it is done at temperatures that can allow botulism to grow. I cold smoke eggs, cheese and meats that will be cooked such as hams and fish that will be canned. I hot smoke jerky dry hams, and dry sausages....James
