Sent the family to Costco this afternoon by themselves (very $$! - LOL) They came home with an item they considered really interesting - 9 large cedar planks. So, besides salmon, what else can you use them for? Have some baby backs in the freezer and was planning a hoisin/5 spice/sambal marinade - can I use them for the browning on the fire? We have a gas grill, will this still work? Can the cedar plank be re-used if I wash it really good? or is there another way to clean it? TIA!
