Guilinggao

Guilinggao, also known as tortoise jelly or turtle jelly, is a distinctive Chinese dessert that also serves as a traditional medicinal remedy. Originally, this jelly was made from the paste obtained from the shells of a specific turtle species, Cuora trifasciata, and was mixed with various herbs, particularly Smilax glabra, commonly known as China root. Due to the high cost of using turtle-derived ingredients, many contemporary versions of guilinggao either utilize more readily available turtle species or omit the turtle shell powder entirely.

It is believed that guilinggao confers numerous health benefits, including improved skin health, enhanced circulation, muscle growth support, itch relief, acne reduction, and bolstered kidney function. The jelly itself is typically dark brown and slightly bitter, but adding a touch of honey can make it significantly more palatable.

Canned guilinggao jelly is available in many East and Southeast Asian countries, and it enjoys popularity in Chinatowns throughout the United States, Canada, the United Kingdom, and New Zealand. Traditionally, the preparation of guilinggao involves boiling turtle shells along with a mixture of herbs for several hours until it achieves a gelatinous consistency. Rice flour and cornstarch are often used as thickeners.

For those interested in making guilinggao the traditional way, the ingredients required include turtle plastron, various roots and flowers, and water, which are boiled down to half their original volume. Alternatively, commercial guilinggao powder offers a more convenient preparation method at home. Some individuals prefer to add extra herbs such as ginseng for additional flavor and health benefits.
