What's the Best Charcoal to Use for Smoking?

Much of the charcoal sold is pressed sawdust formed into briquettes. These generally use a natural, sugar-based binding agent that burns clean. Many cheaper brands add anthracite or coal to the mix for better, hotter burning. Coal is not a good fuel source to cook over but it doesn't affect the flavor much, and it is used in very small amounts.
