Slow Roasting Indirect Over Charcoal

The clue is in the name Charlie Oven; you can roast to perfect using the Charlie Oven.  It's effortless to set up for roasting in the oven; it's a case of set it and then forget it.  Charlie will hold the temperature steady for several hours on a small load of charcoal.  Slow roasting gives the meat time to develop its flavour and allows the meat's texture to improve.  Let's not forget the incredible flavour added by cooking with charcoal.  What's not to like!

Slice across the grain and serve.

Slice the meat against the grain to ensure it is tender.  Cutting across the grain cuts the long strands of tissue.
