Looking to make a delicate fish? Smaller vegetables? Give your food a woodsy, smoked flavor?
In addition to imparting a pleasant woodsy fragrance to your meal, plank grilling is beneficial because the planks act as a barrier to the harsh, direct heat of cooking. This can be especially helpful when preparing thinner or delicate ingredients that might otherwise fall through the grates.
*Also* works for folks with Celiac or other allergies - keep their food separate from the contaminated grill!
