Tamarind, an evergreen tree of the genus Corydalis. Originally from India and tropical Africa, tamarind was introduced to Taiwan Province in 1900, and was used as a vegetable in Southeast Asian countries, but it was cultivated as an ornamental tree in Taiwan Province. Tamarind is not only a seasoning, but also a kind of fruit. China, Guangzhou and other provinces have introduced and cultivated.

In fact, it is commonly known as sour horn. The last time I bought it, the sticker on the supermarket said "Sweet Eyes".
