Empty contents of jar into a mixing bowl and stir to combine. Cut in 3/4 cup shortening until mixture resembles coarse crumbs. Stir in 1/4 cup molasses and 1 slightly beaten egg. Shape dough into 1-inch balls, and roll them in sugar. Place on ungreased baking sheets; bake at 350 degrees F for 10 minutes. Remove from baking sheets immediately. (Cookies will firm quickly as they cool.)
Makes about 4 dozen.
