Tanghulu (simplified Chinese: 糖葫芦; traditional Chinese: 糖葫蘆; pinyin: tánghúlu) also called bingtanghulu, is a traditional Northern Chinese snack of candied Crataegus pinnatifida, also known as mountain hawthorn, Chinese haw, Chinese hawthorn, Chinese hawberry, or shanzha (山楂) in Mandarin Chinese. It consists of fruits covered in hard candy on bambooskewers which are approximately 20 cm long. People often mistake tanghulu for regular candied fruits; however, they are coated in a hardened sugar syrup. This sweet and sour treat has been made since the Song Dynasty and remains popular throughout northern China.
The two common names for the confection literally mean "sugar bottle gourd" and "rock sugar bottle gourd," respectively. The "sugar" or "rock sugar" refers to the sugar coating, while the "bottle gourd" refers to the slight resemblance of the snack to the shape of a gourd.
