hasma

Hasma is a Chinese dessert ingredient made from the dried fallopian tubes of the frog Rana chensinensis^[1], also commonly known as the snow frog or forest frog. Hasma is often mistakenly described as toad or frog fat, since it is sometimes referred to as "toad oil" (Chinese: 蛤蟆油; pinyin: há mǎ yóu).

Production

Hasma is produced primarily in the Heilongjiang, Jilin, and Liaoning provinces in China. Previously available only to Emperors, soups made with hasma are available in North American cities with large Chinese populations and in China , Taiwan and Hong Kong.

Physical characteristics

Hasma is sold dried as irregular flat pieces and flakes ranging from 1-2 cm in length and 1-5 mm in thickness. Individual pieces are yellowish-white in colour with a matte lustre, whose surface may be covered with off-white pellicles. When rehydrated, dried hasma can expand up to 10-15 times in size.

The dried hasma is rehydrated and double-boiled with rock sugar to create a glutinous texture and opaque color. Dried or rehydrated hasma has a slight fishy smell. In its unflavoured form it is sweet and slightly savory in taste with a texture that is glutinous, chewy, and light, very similar to that of tapioca in a dessert.

Preparation

Hasma serves the role of providing texture to tong sui, or sweet soups, as well as increasing the luxury quotient of the soup. These soups are usually flavoured with rock sugar. For the uninitiated, this relatively accessible eating experience belies the exotic sounding nature of the dessert. Hasma is widely featured in dessert dishes in high class restaurants in Hong Kong.

Hasma is most commonly paired in sweet soups with:

• Jujubes (Chinese: 紅棗; pinyin: hóng zaǒ; literally "red date")
• Dried longan fruits (Chinese: 龍眼; pinyin: lóng yěn; literally "dragon eye")
• Lotus seeds (Chinese: 蓮子; pinyin: lían zĭ)

It is also a key ingredient in making "Three snow soup" (Chinese: 三雪湯; pinyin: sān xuě tāng), which consists of:

• Chinese pear (Chinese: 雪梨; pinyin: xuě lí; literally "snow pear")
• Snow fungus (Chinese: 雪耳; pinyin: xuě ěr; literally "snow ear")

Hasma can also be included in more exotic versions of shark fin soup.

Health benefits

Hasma is taken for medicinal purposes in Traditional Chinese medicine. Reported benefits of eating hasma include replenishing vital essence in the lungs, kidneys, and improving skin complexion. Hasma is also prescribed to treat respiratory symptoms such as coughing, hemoptysis and night sweats due to tuberculosis.
