Dumpling Day, also known as National Dumpling Day, International Dumpling Day, or World Dumpling Day, is observed worldwide every September 26. This celebration honors a diverse class of dishes that consist of dough wrapped around various fillings, which can be sweet or savory, and are prepared through methods such as baking, boiling, frying, or steaming. While dumplings are often associated with Chinese cuisine, they have independently developed in many cultures, including Japanese gyoza, Korean mandu, and Italian ravioli. The holiday was established by TMI Food Group, a New York-based manufacturer of dumplings, with the first celebration occurring in 2015. To celebrate, people can enjoy dumplings at restaurants, try different recipes at home, host dumpling cook-offs, or share their culinary creations on social media using hashtags like #DumplingDay.
