Imagery dealing with taste, or implied taste. The 'sensory' imagery includes smell, tactile, etc. Used as a literary device, this type of imagery is intended to add depth and scope to a scene, or in some cases a narrative or symbol usage. It's often effective in many forms of literature. A pastoral setting, for example, can be livened up considerably by not just referring to cows, crops and the occasional farmer. An urban setting can be emphasized by the stench of petrol fumes, greasy diners, etc.
Examples of Gustatory Imagery:
TV cooking shows, where the smells and tastes are relayed through scripts and expressions.|
Recipe books specifying conditions of proper cooking.
