To make this grill, start with greenwood sticks and one large forking branch. Wood choices abound. I used red maple for the photo, but any hardwood or medium-hardwood will work fine. Maple, ash, and dogwood give you lots of natural forks in each branch due to their opposite growth pattern. Just steer clear of buckeye wood, which would make a good fork with its opposite branching, but contains dangerous toxins and tastes terrible.
