Cooked Fish is a food item that is obtained when raw fish is cooked in a furnace. Raw fish can be caught with a fishing rod. Cooked fish cannot be used to heal a tamed wolf nor can it be used to tame ocelots. It is not a very popular food item, although it is good for traveling or when you don't have access to a farm. Cooked fish restores 2.5 times as much as raw fish.
