I don’t know Mac, this grill seems so small do you think they make miniature charcoal for it lol. I have boxes and boxes of coco char I bought about 1000lbs of it. Of course not all was for me it was a pallet share. I think it was a ton of charcoal, half coffee char and half coco char most the other people took coffee char but I still have a bunch of the coffee char too. I thought of getting some of the binchotan but think I’ll try and break up the coco char and give it a try. I bet your skewers were a delight for you friends! What type of meat did you use? I have 1 1/2 lbs of skirt steak what do you think? I’m getting excited about this suya hope I like it. Have a great day Mac looking forward to your cook
