I disagree Flathead. My last one contradicts your statement. Bark was crunchy (not overly so) and meat was incredibly juicy. Maybe I got lucky.
I feel the trick is in the trimming. I always use a whole packer brisket and leave about 1/4" of fat on the flat muscle. I try to trim some of the fat from between the two muscles from the one side of the brisket. Any harder type fat on the edges gets removed too. If you remove too much fat, the brisket will be dry. Made that mistake my first one. Always cook fat side up. Cook the brisket to an internal temp of 203-205 and then tightly wrap in butchers paper. Put it in a cooler with some blankets for a minimum of 2 hours before slicing and serving. It can stay in the cooler a long time and still be plenty hot for serving. I used to use foil instead of butchers paper for wrapping. Bark gets soggy with foil.
Nothing in the smoker this weekend. Heading to Hayward tonight to get molcajete at the Mexican joint in town. Sooo good.
Bought my wife a molcajete bowl for her birthday. She's been wanting one for a while. Gonna try to make our own soon, but have to season the bowl first. There will be some posting of that once we figure it out.
