Used kingsford for the first time this weekend... I had been using royal oak on my newly built uds. Ask the soon to be wifey to pick up some charcoal, and I suggested kingsford blue since I've only used lump.
In testing it, i had all the vents open and it barely got above 300. lump well over 450. The only thing I will say was better is it held temp better, but it smoked a lot more (white). Didn't smell that good, tons of ash.
I better find a way to make it work... I have 40lbs of this dirt.
Oh well... It's better than gas I guess.
