Edible Book Day is celebrated worldwide every April 1, commemorating the birthday of French gastronome Jean-Anthelme Brillat-Savarin, known for his book "Physiologie du goût," which explores the pleasures of food. The event was initiated in 2000 by Judith A. Hoffberg and Béatrice Coron, aiming to blend literature and culinary creativity. Participants create edible books that relate to real books through text, literary inspiration, or form. Groups from various countries, including Russia, Australia, India, and Brazil, actively contribute to the festivities. The event encourages creativity and community involvement, with simple rules outlined on the official Edible Book Day website, allowing anyone to organize or participate in the celebration.
