The ultimate communal feast for birthdays, marriages, religious celebrations, and death anniversaries in Chittagong, Bangladesh, is a Mezban, locally known as a Mejjan. The beef-centric meal, which is eaten by hand, is always free and open to the public. Most of the dishes served at a Mezban can be traced back to the 16th-century Mughal Empire, which first brought the recipes to the region. We visited Chittagong to see how a Mezban is prepared for 40,000 people.
