This is a recipe for Venezuelan or Colombian style chicken tamales. These are unlike Mexican tamales since they are wrapped in banana leaves rather than corn husks. If you absolutely cannot find banana leaves (I buy them frozen sometimes and always find them in a Latino market) you can just use aluminum foil to make the packets. That would be a pity, though, because the banana leaves impart their flavor to these in a most appealing way. These are really easy, but a little tedious to make. The tendency is to make them too big, so curb your enthusiasm! Pun intended.
