Great gunkan

Great gunkan is sushi that is made at level 91 Cooking by combining raw great white shark and kelp for 180 experience. In order to combine the ingredients and make a Great gunkan, one must first unlock the sushi perk in the Aquarium.

When eaten, it heals 1500 life points instantly, and then continues to heal 150 life points per second for 9 seconds, for a total of 2850 life points. This makes the great gunkan the highest healing food in the entire game.

A player cannot eat a second great gunkan until the first one's healing effect wears off. Therefore, it is suggested that players use foods like Rocktail soup, Rocktail, or Shark in combination with Great gunkan for optimal healing in situations that need it. Also note that eating another piece of food while a gunkan's healing effect is active will not stop the healing effect in progress.
