I am smoking a 4 pound brisket in an electric smoker. I know it's a small piece of meat but I wanted to try it before I invested into a bigger challenge. Here are my questions. 1. At what temp do I cook and for how long? 2. How often do I add woodchips? It says not to apply more than 1/4 cup at a time. I have made the mistake of over smoking things in the past. What's a good method? 3. Do I need to wrap it in foil? 4. Any other suggestions?!! Thanks for your help!
