Fènglísū are Taiwanese pineapple cakes, one of the country's most popular desserts and souvenirs. The cakes consist of a buttery, crumbly crust that is filled with a tangy, slightly sweet pineapple jam. The name of the dish is derived from fèng lí, meaning pineapple, and sū, meaning shortcake.
Originally, they were prepared during the period of China's Three Kingdoms Dynasty. The three kingdoms were separated into Wei, Shu, and Wu kingdoms, and the emperor of Shu wanted to marry a sister of Wu's emperor, so he sent a large pineapple cake as a gift.
