Preparation:
In a dish towel or piece of cheesecloth, wrap 1 square of bean curd at a time and squeeze out excess water.  Set bean curd in a mixing bowl and mash well.  Add the remaining ingredients except the oil and broth.  Mix very well and form 8 balls.  Set aside.
Cooking:
Heat the oil in a wok until hot and deep-fry 4 lion's heads at a time until browned on all sides.  Transfer the fried lion's heads to a casserole.  Strain the remaining oil and reserve for future use.  Add the vegetable broth or water to the casserole.  Cover and slowly bring to a boil, then simmer for 1 hour.  The dish should be served piping hot and can be reheated on the stove or in the oven.
