I have some smaller pieces of scrap (aromatic) cedar that I'd like to glue up to make planks large enough for cooking fish on the grill. The way I typically use these planks is to line the bottom of the plank with foil, place the planked fish on the second level over medium heat of a gas grill (@ 350-400º inside the hood) for around 20 min. The plank never chars, but can discolor from the heat on the bottom. The planks are reusable for about 20 trips to the grill or so.
Can thoroughly cured glue contaminate the fish in any way? I was thinking of using polyurethane, just because I have some left over, but otherwise Titebond II.
