A Fruit blast is a gnome cocktail that players can make at level 6 cooking, and grants 50 cooking experience. Making it requires a pineapple, a lemon, lemon slices, an orange, a Cocktail Shaker and a cocktail glass. Players can buy these ingredients at the Tree Gnome Stronghold (for example in Heckel Funch's shop). A cocktail glass may also be obtained from drinking a pre-made cocktail from the bar.
When ashes are added to a fruit blast during the quest Recipe for Disaster, it becomes a dirty blast (You can't add the ashes till after the quest begins. Premade Fruit blasts will not work!), one of the items needed for the quest.
