Overview of Grass Jelly

Grass Jelly (Chinese: 仙草凍, English: Grass Jelly) is a traditional dessert widely enjoyed mainly in Southern China, Taiwan, Hong Kong, and Southeast Asian countries. It is made from Mesona chinensis, a perennial plant in the mint family. The stems and leaves are decocted, strained, cooled, and solidified to produce the jelly. The finished product is blackish-brown or dark green, featuring a unique refreshing bitterness and subtle sweetness. In Taiwan, it is known not only as a popular chilled summer treat but also as a food with health benefits, often consumed to ward off summer heat and for its health-oriented properties.

History and Cultural Background

Grass Jelly is deeply rooted in the folk medicinal food culture of southern China. The primary ingredient, Mesona chinensis, has long been known for its effects such as "relieving summer heat," "detoxifying," and "cooling," and has been widely used as an ingredient in Chinese medicine and medicinal cuisine. In Taiwan, it became popular as a dessert among ordinary people from the late 19th to early 20th century. Since the 1990s, it has been recognized as one of the representative local sweets of Taiwan night market culture, easily available at night market stalls and specialty shops.

In Chinese communities in Hong Kong, Malaysia, and Singapore, it is also known as "grass jelly," and is served in various ways (for example, with syrup, cut fruit, or soy milk mixtures). As health consciousness rises, it has also been reevaluated as a natural dessert that is low in calories, caffeine-free, and gluten-free.

Preparation and Variations

The traditional method of making grass jelly involves simmering the stems and leaves of Mesona chinensis thoroughly, cooling the decoction, and solidifying it. While instant powders and canned versions are now available, many long-established and night market stalls continue to hand-make it, often using starches such as cassava or tapioca starch as a gelling agent.

The flavoring and ways of serving are diverse, ranging from simply cutting the jelly and adding sweet syrup or milk, to serving it as a dessert bowl topped with red beans, tapioca, ginger syrup, or fruits. There are even warm versions served as "hot grass jelly soup" in winter.

Health Benefits and Nutritional Value

Grass jelly contains various phytochemicals, including polyphenols, and has long been known in Chinese medicine for its anti-inflammatory, detoxifying, and cooling effects. Modern basic research indicates it has antioxidant properties, anti-inflammatory effects, and helps gradual elevation of blood sugar, making it popular as a snack to prevent heatstroke in summer and during dieting. It is also characterized by being low in calories, with about 20 kcal per 100g and little fat or sugar.

Social Significance of Night Markets and Grass Jelly

Night markets, such as the Guangzhou Street Night Market in Taipei, Taiwan, are not only places to eat and drink for local residents but also key hubs for community interaction and the inheritance of traditional culture. Long-established shops specializing in grass jelly that have continued for over half a century in these markets are important in both preserving the handmade techniques and supporting local flavors amidst the ever-changing modern urban culture.

Comparison with Related Food Cultures

Grass jelly is often compared to other Asian jelly desserts with different flavors and serving styles (such as Japanese kanten or coffee jelly, or Thai lod chong). All are characterized by being "low-calorie," "refreshing," and "smooth textured," but each is distinguished by its unique aroma and medicinal health benefits.
