So someone asked me what a caper was… I said the most stupid answer” uh, something you put in Italian food. “. Let’s try again, the real answer
According to Wikipedia,
The plant is best known for the edible flower buds (capers), often used as a seasoning, and the fruit (caper berries), both of which are usually consumed pickled.
Capparis spinosa is found in the wild in the Mediterranean, East Africa, Madagascar, South-Western and Central Asia, the Himalayas, the Pacific Islands, Indomalaya, and Australia. It is present in almost all the circum-Mediterranean countries, and is included in the flora of most of them, but whether it is indigenous to this region is uncertain. Although the flora of the Mediterranean region has considerable endemism, the caper bush could have originated in the tropics, and later been naturalized to the Mediterranean basin
