Trinh is a famous chef. since she does not like to share her secret family recipes, she does not write down her special creations, which makes it difficult to remember their ingredients. to aid her memory, she has created a unique "mental walk" that she takes to recall each recipe. for each one, she has a familiar "route" she can imagine walking through (e. g., from the end of her driveway to her living room) where she places each item in the recipe somewhere along the way (e. g., fish sauce splattered on the front door). by doing so, trinh is using to organize her memories.
