Smoking some al fakher cherry with mint. I would post an image but it says "your forum has disabled image sharing" [emoji53] seems to be an issue for me for a week or so now and idk why since other people still can post pics.
I use a small coil coal burner.
Blood cell shaped sounds like quick lights..
If not, maybe try putting some foil around/over the coals when you're heating them to keep the heat directed at the coal more and it may help.
