Potato jelly is a special flavor snack of Datong. To get the most of it, the potato dough must be elastic in texture.

The capsicum is another secret weapon. Local workshops have their own unique recipes to cook peppers, which has contributed a lot to the delicious taste.

Potato jelly is soaked in water before it is served to customers. The ingredients are diverse, including salt water, soy sauce, chilli oil, vinegar, sesame oil, gourmet powder, mustard, and chopped green onion.

It can also be served with cucumber strips, radish strips, caraways, and bean curd strips to make it even tastier.
