Jealous Devil is one of my favorite lump charcoals to use. Easy to light, burns for a long time, low ash, and consistent behavior from bag to bag.
I tend to rotate through different kinds of lump because I apparently enjoy trying out new things instead of dialing in a workflow with one or two kinds of lump, but Jealous Devil lump is one of the several varieties I go back to when I need something I know I can count on.
