Stone-ground rice roll is a kind of rice roll made by using traditional stone mill to make rice slurry. The unique design of the stone mill makes the ground rice milk particularly delicate. The chef adds ingredients such as pork, eggs, shrimp, beef, etc. to the rice milk, then uses a rice roll machine to quickly steam it, and finally adds special sauce. It tastes tender, smooth and fresh, and is one of the most popular breakfast dishes in Guangdong.
