According to Jim Thompson :
You reminded me. Many years ago I had a mesquite stump to get rid of
(mesquite is *very* hard).

Sawed it off as flush to the ground as I could manage with a big
logger's saw, then dug around the roots to expose them.

Covered the whole thing with charcoal and lit it off.

Daily I'd come home from work and add more charcoal.

Did you BBQ with it daily too?

You should have ;-)
