I've done some experiments in my "other" smokers to see if there was a difference between the two. Lump produced no noticeable flavoring.
Kingsford gave me a light smoke flavor that was easily covered by rubs sauces etc. It wasn't the most pleasent flavor, but wasn't too bad.
I did a rib roast tonight in the egg using Kingsford (out of lump). The off taste was very pronounced. Not good. The other day I posted about the smell of incomplete combustion when I shut the egg down while doing steaks. There was Kingsford in there that day. I'm sure that's what I smelled. Anyone know where to find lump in south Kansas City. My usual source quit carrying it.
