Early on I had no problem getting the XL to 600+.
Lately I have not been able to get it past 600.
Today I only could get 550 degrees.
I was using the XL lump reducing ring (bar design)
I had cleaned out all the ash.
I light in 3 places with paper towel and olive oil.
I let it burn for about 10 minutes dome open, bottom vent fully open, fully open.
I close the lid and after about 20 minutes 550 was as high as it was going to get.
All of the charcoal was glowing bright orange.
I hate to fill the entire firebox for a superhot sear.
But is that the solution?
