In a large bowl, beat the brown sugar, butter, buttermilk and egg until creamy and well blended. (The mixture may look curdled which is fine.)
Stir in the flour, baking soda and salt just until blended.
Cover and refrigerate for at least 1 hour.
Position an oven rack in the center of your oven. Preheat oven to 400F degrees.
Drop cookie dough by rounded teaspoonfuls, about 2 inches apart, onto ungreased cookie sheet.
Bake in the center of the oven until almost no indentation remains when touched, 8 to 10 minutes. Remove from the oven and immediately transfer the cookies to a wire rack to cool.
Repeat with the remaining cookie dough, being sure that the cookie sheets are cool before placing dough on them.

When I have more time, I plan on making a small batch of the glaze and trying it on a few.
