“Gustatory” is an adjective concerned with anything related to taste, joining other sense-related terms such as “aural” (hearing), “olfactory” (smell), “visual” (sight), and “tactile” (touch). “Gustatory” can describe the quality of a taste — sweet, salty, sour, or bitter — or it can refer to the mechanics and process of tasting something. In Disney’s 2007 film “Ratatouille,” the main (animal) character Remy seems to have a condition called “gustatory-visual synesthesia,” meaning he can “see” taste and flavors. This makes him quite adept at throwing together fantastically inventive recipes. The adjective “gustatory” may also have inspired the name of Remy’s idol, the fictional legendary chef Auguste Gusteau, as it comes from the Latin verb “gustāt-,” meaning “to taste.”
