National Mofongo Day is observed worldwide every September 24, celebrating the Puerto Rican dish mofongo, which is made from mashed plantains and often includes pork rinds or bacon. The dish has roots in West African cuisine and was introduced to Puerto Rico by African slaves in the 16th century, utilizing limited ingredients available at the time. Mofongo is traditionally prepared by frying, roasting, or boiling green plantains, which are then mashed with fat and spices in a pilón. The holiday was established in 2021 by Puerto Rican chef José Mendín, who sought to honor the dish and its cultural significance. Celebrations can include dining at Puerto Rican restaurants, making mofongo at home, or hosting themed parties. The day encourages sharing the experience on social media with the hashtag #NationalMofongoDay.
