"We make more than one tonne of Osmania biscuits every day," Irfan, a third-generation businessman, told IANS.

The bakery also supplies the biscuits to cities like Chennai, Bangalore and Mumbai.

Though Osmania is a favourite for all seasons, sales particularly go up during winter when people enjoy this with hot tea.

Nimrah Cafe near the historic Charminar is another popular place. From a petty trader doing business on the footpath to a tourist visiting Charminar, everybody relishes the cookies with chai. From early morning to till late in the night, the cafe does brisk business.

The biscuit is made of maida mixed with sugar, salt, milk powder, ghee, baking powder, and other ingredients.

Traders also buy Osmania from Nimrah for their business in various parts of Telangana and Andhra Pradesh.
