They are used to make a number of deserts and snacks. In Northern China they are often sold dipped in a sugar candy coating on a wooden skewer  much like toffee apples are  in Europe and are called 糖葫芦 (tanghulu).

They have been associated with various medicinal properties especially as a digestive aid.
