Pitha Utshob (Pitha/ Rice cake event)- This is held in winter in my country, people make hot pitha rice cakes/candy floss live, eat it with chaat/curry.  You can do something similar to it involving foods from Bangladesh/ India/ Pakistan/ Sri lanka etc.

Background: Winter in the UK implies hot chocolate, snow, and Christmas. Winter back home in Bangladesh is much more different. The word “pitha” in Bangla refers to an indigenous food item that is nationally popular. Sweet dishes like bhapa pitha, patishapta, dudher shondesh, etc are the most common examples. “Utshob”, on the other hand, means festival. Thus, combined, pitha utshob is a glorious exhibition in Bangladesh during the winter season where people get together to set up stalls and sell their homemade pithas.
