The coffee lump charcoal from Dennis is amazing. As soon as I got it home I made a small test fire for grilling a steak. If one thrills to fire, this charcoal is irresistible. One will look for excuses to play with it.
I ordered a Broil King KA5565 Charcoal Caddie Basket to cradle a smaller, higher fire, and it came today. In my 23" KK it rests on the charcoal basket, with its rim about 3" below the lower grill grate. It has a capacity of about two quarts. Shown, I filled it with less than two pounds of coffee lump, about $2.50 USD at the scale we ordered. The KK is so well insulated, this will easily maintain roasting temperatures for several hours.
I'm looking forward to quick fires to prepare single ingredients, such as grilled eggplants or peppers, or to grill a single piece of meat. With this charcoal basket, my KK will be my grill of choice for any scale. And coffee lump will be my fuel of choice.
