help me perfect this.

TAI. I tried the Naked Whiz recipe called Bar Towel Tenderloin. I had two tenderloins tied together and rubbed with my favourite rub. All the prep work went fine. I am just trying to perfect the actual grilling of it. Was using both eggs, large had an indirect cook of Parmesan Potatoes, and also AF'ed corn. The small egg was used for the tenderloin. The real estate was needed for the corn and potatoes on the large. So I used about 3 lbs of salt on the tenderloin, 2 lbs of Kosher Salt and then I had about 1 lb of table salt, I mixed it all together and put the meat in the towel and tied it together. The meat was placed directly on the coals. It was a tight fit, had to bend the meat into a horseshoe type pattern. Let it cook, the recipe says to grill about 30 minutes, and they suggested not to turn it over, so went with that. Used the thermopen to check temps. About 25 minutes into the cook, the towel had secured itself onto the fire ring, and I had to pry it off with a screwdriver. Temps creeped up on me and I pulled it a little late. So the end result was a little dry, but not all bad. We had some fig jam reduced and made a drizzle for it.
