What is Mam Nem?

Mam Nem is a traditional Vietnamese fermented anchovy sauce, known for its bold, pungent aroma and rich umami flavor.

It is a staple in Central Vietnamese cuisine, particularly in Da Nang and Hue, where it is commonly served as a dipping sauce for pork rice paper rolls (Banh Trang Cuon Thit Heo), vermicelli noodles (Bun mam nem), and grilled meats. Despite its strong aroma, Mam Nem is loved by those who appreciate authentic Vietnamese flavors, making it an irreplaceable part of the country’s culinary identity.
