Lao Sun's mutton steamed bun is delicious and fragrant, not only because of the good raw materials, but also because of a set of secret know-how that is not easy for others to imitate. This set of techniques can be summarized into three major links: one link is to cook meat; One link is to make cakes, sometimes called "栲栳 baked cakes"; One part is cooking. The process of cooking meat, soup and steamed buns into a bowl of mutton bubbles is very delicate and wonderful. "The customer breaks the bun, the chef cooks, the soup is set by the bun, the soup is timed, and the flavor is fragrant", this is the secret of the chef of the old Sun family, and it is also the food in the mouth of the diner, and the two sides have reached a tacit understanding with this.

The bun is evenly weighed like bean grains, the meat is cut into a standard like a fish, the blister vermicelli is netted to catch the "fish", the garlic sprouts are put into the bowl like a point of emerald, and then, the hand spoon hooks the soup into the scoop, the soup boils after the bun, boils over high heat, and then seasons and dries sesame oil. The flame is whirring, the steamed meat is boiling, the hand spoon is boasting, the fire is ready, the scoop is put into the bowl, and the juice is adjusted.
