In a large bowl beat together the butter and sugar until creamy. Add molasses and egg, beating until well blended.
In medium bowl, blend flour, soda, salt, cinnamon, nutmeg, ginger; add to molasses mixture, mix well. Cover and chill at least 20 minutes.
Form dough into 1 inch balls, roll each in sugar, place 2 inches apart on cookie sheet.
Tip: To make uniform balls that bake evenly, use an ice cream scoop.
Bake at 375 degrees for 6-8 minutes. Let stand 1 minute before removing. Makes around 5 dozen. (I tend to get 3 dozen, but they're so good I like a bigger cookie)
Notes
To make Gingerbread, just cut 1/4 cup butter and increase the molasses.
