Burnt giant flatfish is the result of accidentally burning a raw giant flatfish while attempting to make a giant flatfish. Cooking a giant flatfish requires 30 Cooking, and burning it will become less common with a higher Cooking level. The tier of the fire used to cook it also affects the burn rate.
Unlike most other items in Dungeoneering, burnt giant flatfish dropped on the ground will disappear after 30 seconds.
