Burnt crayfish

Burnt crayfish is the result of accidentally burning a raw crayfish while attempting to make a crayfish. Cooking a crayfish requires 1 Cooking, and burning it will become less common with a higher Cooking level. Crayfish stop being burnt at level 33 Cooking.

The burnt crayfish has no use whatsoever, although you can unsuccessfully attempt to eat it. Like most other burnt food, it is tradeable to other players but not on the Grand Exchange.

A hidden update on 4 March 2013 made all burnt crayfish stackable.
