Preheat oven to 325 degrees F (165 degrees C).

In a medium bowl, mix herb-seasoned dry bread stuffing mix with hot water. Gradually mix in pork until blended with the stuffing mix. Stir in onion, celery, egg and baking powder.

Shape the mixture into 1 inch balls. Place the balls on a large baking sheet, cover with foil and bake in the preheated oven 15 minutes.

Remove foil. Raise oven temperature to 350 degrees F (175 degrees C). Continue baking 25 minutes, until golden brown.
