Why are food memories so vivid?

Instruction:
Why are food memories so vivid? What is the difference between ordinary memories and “food memories” – if there is a difference? Use the food memoirs of Brillat-Savarin, Proust and MFK Fisher as examples.(see attached files, look for writing, dont have to use in essay) Why do food items such the madeleine have such iconic status in our memories? What does being an “iconic food” mean? Why does food play such an important part in building our identities?

The iconic food for me I choose is Kaiseki cuisine.
