Gustamancy

A type of Sensecraft involving the manipulation of one's sense of taste. Sometimes called "tastecraft." Associated with the color blue.

Can be used to enhance or dampen one's ability to detect certain tastes (salty, sweet, bitter, etc). With practice, it can even be used to add or remove more complex combinations, such as the taste of a particular ingredient. Taste hallucinations can create any flavor imaginable, even if the target is not actively eating anything.
