A longevity peach, or shoutao, is a type of lotus seed bun, sometimes with a filling made of red bean paste or lotus paste. It is white with a red dyed tip with a crease along the side, mimicking the shape of a peach. Occasionally, bakers add green decorations that mimic leaves.[1] The longevity peach is a representation of Peaches of Immortality. According to Chinese folk legends, these peaches ripen every thousands of years, and grant immortality to humans when consumed.[2]
The pastry is typically served at the birthdays of elderly people to celebrate their achievement in having reached old age.
