What is "hasma"

Hasma (Harsmar, Hashima) is a Chinese and widely Central Asian dessert ingredient made from the dried fatty tissue found near the fallopian tubes of true frogs, typically the Asiatic Grass Frog (Rana chensinensis). Because of its whitish appearance, Hasma is often mistakenly described as "snow frog fat". The Western pharmaceutical term is Oviductus Ranae.
