Banana roll is a common Chinese pastry found in Hong Kong, and may occasionally be found in some overseas Chinatowns. The pastry is soft and made with glutinous rice. Ingredients may vary depending on where it is purchased. Each roll is a vanilla flavored circular tube, slightly bigger than an adult sized index finger, thus resembling banana. Sometimes it may have a cinnamon swirl filling. At other times it may have a filling that consists of a very ripe (but not rotten) banana diced finely. Occasionally the more traditional red bean paste may be used.
