A type of traditional South Asian (especially Bengali) sweet or savory cake, often made from rice flour, coconut, or other ingredients.
Pitha can be steamed, fried, or boiled, and is popular in Bangladesh, India (especially West Bengal, Assam, and Odisha), and other regions. If the café is serving it, it’s probably a sweet version, like chitoi pitha (thin, crepe-like), patishapta (rolled with coconut and jaggery), or bhapa pitha (steamed).
In Los Angeles, you can try pitha in the Little Bangladesh neighborhood where eateries such as Halal Cafe 71 are known to sell them.
