Quick Answer
If a plank starts to burn during cooking, immediately remove it from the heat source and discard any charred or damaged areas, then continue cooking with a new plank or a heat diffuser to prevent further damage.
Assessing the Situation
If a plank starts to burn, assess the damage quickly to determine the extent of the burn. Look for any charred or blackened areas, as these can be a sign of the wood breaking down and releasing chemicals that can affect the flavor and safety of the food. If the burn covers more than 25% of the plank, it’s best to discard the entire plank and start over.
Preventing Further Damage
To prevent further damage, remove the plank from the heat source immediately and discard any charred or damaged areas. If the burn is minor and only affects a small portion of the plank, you can try to trim the damaged area off with a sharp knife or a pair of kitchen shears. Be cautious when handling hot planks, as they can cause serious burns. If you’re cooking over an open flame, consider using a heat diffuser, such as a metal griddle or a stainless steel tray, to distribute the heat more evenly and prevent hotspots that can cause burning.
Cooking with a New Plank
If you need to start over with a new plank, make sure to clean and prepare it properly before cooking. Soak the plank in cold water for at least 30 minutes to rehydrate the wood and reduce the risk of burning. Then, dry the plank thoroughly with a clean towel and lightly oil it with a neutral-tasting oil, such as canola or grapeseed oil. This will help the plank cook more evenly and prevent sticking. When cooking fish on a plank, aim for a temperature of 400-425°F (200-220°C), and cook for 8-12 minutes, or until the fish is cooked through and flakes easily with a fork.
