Well, yesterday I went to the store to get charcoal in prep for the St Pat brisky cook. I wanted to use mesquite...I've been in a hickory and apple wood rut lately. They were out of K comp. So, I picked up a bag of K with mesquite chips formed into the bricks. I imagine it's blue with the addition of these chips. First time for me not using chunks of wood intermixed and on top of coal. I just put a 6# brisky on ...so we'll see. Anyone else use this stuff?
