I got a albs flat brisket and planning to smoke it tomorrow. How much coal should i use for approximately 8 hour cook? I have Stubbs lump charcoal and Kingsford Blue bag briquettes. Which one and how much would you reccomend? I used Stubbs last weekend for the first time to cook Spare ribs. I filled the ring all the way to the top and took the center out to start in the chimney. Throughout the cook I had white smoke coming out through the went. I know it is bad news, however the food didn't taste bitter. Now I am thinking it was a steam from the water pan since the out side temperature was around 25-27F. The charcoals were difficult to start, but temperature was very very steady for 7 hours. I never had good luck with briquettes, whenever I use them they will burn hot for the first 3 hours, but than temperature would drop bellow 200, unless I add more coals. Not sure what and how to properly use them for the brisket tomorrow. Please help.
