Shark soup is a type of food that was added to RuneScape with the update of Player-owned ports, but is currently unable to be made by any means. It is supposed to heal 1,400 lifepoints, apparently less than its presumed ingredient, a Shark.
Following the pattern set by Rocktail soup - the properly released counterpart of Shark soup - it is assumed that the ingredients of this item would be a Shark and some Spices. It would likely be able to be created in the Workshop of the ports, after building the respective upgrade.
After the item was released along with Player-owned Ports, this item was uncraftable by any means, even though it was also present in the Grand Exchange's list of items. Having a starting price of 1 coin, it began rising steadily as unfulfilled buying offers were placed.
On 20 August2013, the item was removed from the Grand Exchange with its price at 470 coins, and any reference to the item was removed from quickchat.
