Shanghai snacks and delicacies include three treasures: crab shell yolk, snails, and fried chicken steamed buns. Next, I can introduce to you some of Shanghai's "three treasures" of delicacies.

Crab shell yellow is named after its yellow color, which is similar to crab shells. Crab shell yellow is made from pastry and yeast. It is first formed into a flat round cake, coated with sesame seeds and then baked on the walls of the oven. This cake tastes delicious, salty, and sweet, and has a flaky, crispy crust. Some people wrote poems praising it as "before the baker smells the incense, the pastries fall one after another at the entrance." Crab shell yellow has a salty and sweet taste. Salty ones include scallion oil, fresh meat, crab powder, shrimp, etc. Sweet ones include sugar, rose, bean paste, date paste, etc.

Shanghai’s snails are a famous specialty snack. This snack is made from longan snails from Tunxi, Anhui. It is big, fat and thick-meaty. First, put it in clean water for two days to spit out the silt. Then put it in a pot and cook it for a long time with fennel and cinnamon. Finally, put the cooked snails into old-age fragrant distiller's grains and make it with distiller's grains. This kind of snail is brown-grey in color, has tender meat, and the sauce is mellow and delicious. It is very popular.

Fried chicken steamed buns are a special snack in Shanghai. The snack is made from fermented white flour and filled with cooked diced chicken breast, minced pork and pig sandwich, frozen pork rinds and sesame oil. The tip of the wrapped and kneaded steamed buns should be dipped in chopped green onion and sesame seeds. The surface should be brushed with ordinary oil and cooked in a pan. The product has a plump shape, with yellow sesame seeds and green onions on top, making it soft and delicious. The bottom part is crispy and delicious, the filling is thick and juicy, and the more you eat, the better it tastes.
