Has anyone used homemade charcoal for grilling specifically for a master built gravity grill? I made my own charcoal as a fun project out of alder. However I have a concern that it's too brittle compared to lump charcoal you get from the store. I probably won't use it but I'm curious if anyone has. At least not in the gravity grill. Oh also the home made charcoal lights fast! Haven't used it for grilling yet.
