Re: Home made coals safe?
using hot coals from a fire definitely works... but as others have said, it becomes this ridiculous heat management juggling event. you can basically cover the top of the bowl with hot coals and smoke just fine... but they'll be completely dead in 3-5 minutes, throw those back in and start over, every 3-5 minutes. it's just not relaxing at all. i've even tried using the "natural, lump hardwood charcoal" that i grill with. it works, without odd flavor/odor, but they just don't last.
i would not, however, worry about multiple insects having peed on them... fire is a pretty good cleanser
