Combine first four ingredients in a large mixing bowl (flour, oats, wheat germ, coconut). Then blend together separately all the rest of the ingredients except the walnuts/raisins. Add the blended liquids to the dry ingredients and mix well. Add the walnuts and/or raisins and mix in. Spread finished product out on 2 greased cookie sheets and bake 1 hr at 250 degrees F or until dry and golden. Store in covered containers. Makes 2 1/2 to 3 quarts at 1 cup per serving (less for children). Very filling! Lasts a long time if kept in a cool, dry place.
