Imagery refers to mental pictures in your mind, or to words and descriptions that create mental pictures. Gustatory imagery, in particular, refers to imagery related to the sense of taste. In other words, with gustatory imagery, the writer describes what is being tasted. Those descriptions should create pictures in your mind that make you think about that taste.
Examples of gustatory imagery are any descriptions that you read that can almost make you taste what the author is discussing or that can allow you to imagine what something tastes like.
Here are some gustatory imagery examples:
These are all examples of gustatory imagery. The idea behind examples of gustatory images is to allow the reader of the words to picture eating the food and to almost imagine what the food tasted like. A mental picture can be formed when descriptive language is used to create rich gustatory imagery.
