The fuel I use most often when grilling/Smoking is Wicked Good Weekend Warrior Lump. Great Stuff. I've bought two pallets over the past three years. The last time I got the lump I also picked up a pallet of the briquettes. Naked Whiz really like them. Anyway they burn fine and are easy to light, but there is one problem. They leave an off taste on the food. Anyone else have this problem? Used some last night in the mini smoker. Lit off about 16 briqs, added some apple wood, let the smoker get hot and added the gigantic lasagna fatty. About an hour in added 4 cold briqs to the fire, made a little white smoke and then turned blue. When the fatty was all cooked I could taste something was not right. The wife thought it was delicious. Any thoughts or suggestions?
