Nian gao

Nian gao , sometimes translated as year cake or New Year cake or Chinese New Year's cake, is a food prepared from glutinous rice flour and consumed in Chinese cuisine. It is also simply known as "rice cake". While it can be eaten all year round, traditionally it is most popular during the Chinese New Year. It is considered good luck to eat nian gao during this time of the year because nian gao (年糕) is a homonym for "higher year" or "grow every year" (年高), which means "a more prosperous year". The character 年 is literally translated as "year", and the character 糕 (gāo) is literally translated as "cake" and is identical in sound to the character 高, meaning "tall" or "high". In Mandarin (though not all Chinese languages), Nian gao (年糕) also is an exact homonym of "sticky cake" (黏糕／粘糕), the character 黏／粘 (nián) meaning "sticky". This sticky sweet snack was believed to be an offering to the Kitchen God, with the aim that his mouth will be stuck with the sticky cake, so that he cannot badmouth the human family in front of the Jade Emperor. It is also traditionally eaten during Chinese New Year. Originally from China, it spread to or gave rise to related rice cakes in Southeast Asian countries and Sri Lanka due to overseas Chinese influences.
