I'm relativly new at REAL BBQ and need some confidence building since I am not satisfied with my results, so far.
While cooking both brisket and butts with a BBQ Guru, the bark gets a resin or bitter oily taste, while the inside is moist and tender. I'd liken the taste to the smell of smoke from freshly starting Kingsford charcoal. I light the charcoal in a chimney with MAPP gas, then let it get a very good start before spreading it out on the grate. I then add more charcoal to fill the fire ring and wait for it to fully light and turn grey all over. I drop on some smoke wood, Mesquite and Apple (about two hands full) Then I assemble the bullet and close all the bottom vents and close the top vent to about 1/2. I wait for the temp to drop to near cooking temp and then load the meat quickly.
The Guru does a great job at controlling the temperature for the rest of the cooking session. The drippings fall on the charcoal below. I monitor the cooking temp and the internal meat temp and stop cooking when the meat temperature meets the criteria for proper "doneness".
The bark is very dark black, even tar like. And it has the off taste described above. I'm thinking of trying mesquite lump charcoal, but it is harder to light and burns inconsistantly.
If anyone knows what I'm doing wrong, or needs more details for a diagnosis, please reply to the forum.
