1 cup margarine
1 cup Domino's dark brown sugar (packed with a spoon)
2 cups Brer Rabbit green label baking molasses
1 cup buttermilk
2 even TBSP Arm & Hammer baking soda
1/2 tsp. McCormick ground ginger
7 cups flour
In a mixer, cream margarine and brown sugar. Add baking molasses, baking soda, buttermilk and ginger. Mix until smooth. Add 7 cups of flour one at a time. When it gets too stiff for mixer, use a wooden spoon and mix the rest by hand. Drop heaping teaspoonsful onto greased cookie sheet.
Beat the egg in a cup with a fork. Using a teaspoon, put a little bit of egg on the top of each cookie and smooth it down with the back of the spoon so cookie is slightly flat. Bake at 375 degrees for about 15 minutes.
