Eid-ul-Fitr
In some villages it’s called Semai Eid.
Eid-ul-Fitr in Bangladesh starts at the shemai pot. Before the family walks to the Eid gah, breakfast is a bowl of semai, and in some rural areas the festival is simply known as Semai Eid.
Through the rest of the day it's what gets offered to every guest who comes to the door. Alpha Laccha Semai is made for that one fixed moment in the calendar, and for every craving in between.
