Petrona Carrizo de Gandulfo (June 29, 1896 – February 6, 1992),[1] better known as Doña Petrona, was an Argentine best-selling cookbook writer, home economist, television chef and businesswoman who was famous for "her elaborate dishes, provincial accent, matronly figure, didactic tone, and bossy treatment of her assistant [Juana Bordoy], as well as her responsiveness to fans".

[6] Doña Petrona built a multimedia empire around her own name and used it to establish herself as the most popular and commercially supported celebrity chef in 20th-century Argentina.

[5] Her figure has been compared to that of Isabella Beeton in the United Kingdom, as her "popularity stemmed from her ability to tap into the desire for 'expert' domestic advice among the emerging middle classes".

[10] Her closest counterparts can be found not in other Latin American nations but rather in the United States, having points in common with Fannie Farmer, Betty Crocker, Irma Rombauer and Julia Child.

However, due in part to Argentina's more concentrated media market, Doña Petrona's success "compares to not one, but all the major legends of home cooking in the United States put together.
