1. Remove the husks from the corn and set aside. Scrape the kernels from the cobs and reserve the cobs.
2. Put the kernels in the container of an electric blender or food processor and blend or process very briefly at low speed. Do not liquefy. Scrape from the blender into a bowl and add the egg, sugar, salt, cream cheese, butter, baking powder, and cornmeal. The mixture should be on the heavy side.
3. Divide the mixture into 12 and place each portion on a double husk, roll to enclose, and then wrap in aluminum foil.
4. Place a layer of corncobs in the bottom of a large pot and add the water. Place the packages on top of cobs, cover, and steam for 45 minutes, or until done.
