Re: CH natural coals problem
Are you guys reading what he's saying?
I think he's experiencing what coconut coals do. CH naturals do this, coconaras do (but not as noticeable i dont think).
Its just like when u put them on the bowl, the bottom side will turn black. Maybe the material is just really temperature dependent. But i know what the original poster means, i just accepted it. Make sure the core of the coal is red and i go with it.
By the way, try using a windcover or something else on the stove to help speed heating times.
