My hometown is Tianjin. Speaking of specialties, I have to mention the gourmet Goubuli steamed buns, which are definitely famous throughout the country.
"Thin-skinned and large stuffing with eighteen pleats", the snow-white bun skin is thin but very soft. Just poke it with chopsticks and it will open the small opening. With the slightest heat, the filling mixed with oil and flowers slowly simmers.
It flows out slowly, making people move their index fingers.
When I took a bite, I saw that the pork filling was hand-chopped. It was very smooth and tender, but with a grainy and meaty texture. It also had the unique soy sauce aroma of Tianjin. I could eat five or six of them in one sitting. It was so good.
