A Bailna or rolling pin is used to roll out doughs to make roti or bake. Yes, even pizza doughs. It is also handy for making crumbs easily. Just place crackers or toasted bread in a paper bag or wax paper and crush it with the rolling pin.
This utensil is made of wood, but nowadays, it is commercially made out of plastic. But the wooden bailna, from my experience, is the best.
