Preheat oven to 350 degrees. Liquefy liver in blender. Mix molasses, garlic, anise, wheat germ and brewer's yeast. Add liver. Stir in 1 1/2 cups wheat flour to mixture. Dough should be very stiff. If it isn't, continue adding a little flour at a time until it is. Roll dough out on board and cut out cookies with Christmas Cookie Cutters. Bake until golden brown. Turn off oven and leave cookies in oven overnight to harden.
Alternate method: Spread dough evenly over cookie sheet. When baked break into chew size pieces.
