Today was my first try at Hot & Fast Pork Butts/Shoulders on my lang 84. Got the smoker up to 350-375 no problem but have about 1 1/2 I found it smoking pretty good and when to check and and I had a grease fire. When using the "hot and fast" method is necessary to cook the entire time in tin pans? I thought i would cook on the grates for 2 hours and then pan them and foil at about 3-4 hours. Any thoughts or comments would be great.
