Buddha's hand citron, also known as the fingered citron, is one of the oldest varieties of citrus. It looks like a lemon with long segments growing from it. Its name is derived from its unusual shape, which also resembles a hand position for prayer. A single fingered citron can cost $25 but go as high as $170 depending on how well-shaped and magnificent it is. The farmers in a small Vietnamese town are reaping the financial benefits, but at what cost? And why exactly is Buddha's hand citron so expensive?
