Below I started a theread on making chipolte peppers. I did these on my 3 tier rack and they have taken longer than expected. I have done these several times in small quantities usually being done within 26 hours. The only charcoal I had was Royal Oak. This is not my favorite but it is cheap at Wal Mart. I hoped the royal oak would last for 30 hours @ 150 degrees (I was dountful). Well I am now @ 36 hours and the fire is going strong @ 150. Most of the peppers are done but I expect the rest won't be done til lunch or dinner today. I never in my wildest dreams expected Royal Oak to last this long. Oh yea, I am using a BBQ Guru. I may get 46 hours out of one load.
