We now have stock of Alder and Cedar Grilling planks. Cooking on a plank instead of on a metal tray imparts extra flavours that you just can't replicate any other way. Soak the planks for at least 12 hours in advance but don't use them dripping wet. The soaked wood will create a humid evironment around your meat and will slow the burn down if you use it in a Pizza Oven, Charcoal grill or Hooded BBQ.
We also have Cedar wraps that will achieve a similar result to the planks but they also hold in the moisture better and because they are wrapped around the food you will reduce the potential of burning the meat.
Have a look for the Planking recipe books as well for more inspiration.
