Place liver, oil, water, garlic and the optional goodies in a blender or food
processor, and liquefy them. Pour them into a bowl, add flour until you have a
stiff but sticky batter. Pour into greased pan. Bake at 350 degrees for at least
1 hour. After 1 hour cut a small slice and if any pink is showing, return it to
the oven for about 15 minutes more. Must be well done.
Be warned that once a dog tries this cake, they have been known to stand in
front of the oven drooling while it is baking.
