In 1993, Antonia Heredia Herrera, archivist and theorist, and Mercedes Reguera Ramírez co-authored a book entitled "Recipes from Sevillian Cookery" (Recetas de cocina sevillana), published by Seville's Provincial Council's Archives and Publication Service. The book was a compendium of recipes from all over the region, compiled from recipes sent in by ordinary people. The recipes reflected what those individuals ate at home and the knowledge that had been passed down from their ancestors. It also included a notebook for readers to make their own archive of recipes, passed down from generation to generation.
