The snack got its name from Ear-hole Street in Tianjin's Bedaguan, where it was invented and sold. The Ear-hole Fried cake dates back to the late Qing Dynasty, over 100 years ago.
The cake is made of carefully leavened and kneaded glutinous rice dough. The filling is bean paste made from quality red beans. The pastry of the finished cake is golden in color, crisp and crunchy, while the filling is tender and sweet, with a lingering flavor.
