Been egging about two months now and am now seeing the difference in lump coal brands or maybe it just inconsistent? I have used five different brands and find them all different. My latest brand messed me up with a low and slow for a party! I have cooked two 7 to 8 pound pork butts 22 hours. Low(215)and slow to perfection using the Green Egg lump and had 1/3 of the coal not used during the cook. Now i want to duplicate the product, but cook four butts instead of two. I empty and clean out my fire and ash box and fill my fire box with Royal Oak lump thinking it is the same as Green Egg ?? And i begin my "low(215) and slow" and as i reach my 20th hour i find my temp. dropping and my fan constantly running---I'm out of fuel ?!!!? Now i need another hour to reach my internal of 195, but now i have to stop the cook, remove the food and refuel and restart my egg! Of course the internal temp. of the butts drop back 8 degrees and it actually takes two hours to finish the cook. My question is -- is it the manufacturer or is lump coal this inconsistent? But then cooking four butts instead of two must enter somewhere into the problem -- it requires some energy source to cook each pound of product... From what i have found the Green Egg lump and the Publix brand seem most consistent - but i haven't the experience you all have ?? I am considering bringing the Royal Oak back???
