Madeleine cake (also known as shell cake) is a snack with full French flavor. Shell cake has a long history. It was originally just a family snack. It is rumored that in 173, the gourmet Polish king Leiguchengski, when he was in exile in Merseyside, one day, his personal chef slipped away. I didn't expect it to win the favor of Reguchensky, so I used the name of the maid Madeleine for the name of the snack, and Madeleine is the real name of the shell cake. It is Proust, the great French writer, who pushed the shell cake onto the historical stage. Proust's taste memory of shell cake led him to write a long literary masterpiece "Memories of Time Past", which is a book to fight against forgetting. And 5E Madeleine means to recall the past and miss the past.

One of the three pillars of modernist novels, Proust's Memories of Time Past is the origin of this novel: One day, Proust ate a snack from Madeley by chance, and as a result, a very familiar smell came from the bottom of his heart, which suddenly revived the memories of all teenagers and youth, so he followed his "stream of consciousness" across time and space to return to the past, and the novel written was considered to be a great masterpiece.
