Swann’s Way (Remembrance of Things Past, Volume One) can be downloaded for Free at Google Books (no kindle needed, just a computer or tablet). Proust talks about his “madeleine” on p.61:
“And suddenly the memory returns. The taste was that of the little crumb of madeleine which on Sunday mornings at Combray (because on those mornings I did not go out before church-time), when I went to say good day to her in her bedroom, my aunt Léonie used to give me, dipping it first in her own cup of real or of lime-flower tea.”
Enjoy the book or a madeleine or both!
