Butter Cookies With Icing

Preheat oven to 350 degrees F.

In a bowl with an electric mixer, beat the butter with the sugar until light and fluffy. Beat in the egg and lemon peel until just combined.

In a bowl, sift together the flour and the salt. Add the flour mixture to the butter mixture, a little at a time, and beat until combined well.

Divide the dough in half, wrap in plastic, and chill for 2 hours.

On a lightly floured surface, roll the dough 1/8 to 1/4 inch thick and stamp out desired shapes with cookie cutter.

Transfer to ungreased baking sheets, spacing 1 inch apart, and bake for 7 to 9 minutes or until lightly golden around the edges.

Let cool for 5 minutes on the sheets and transfer to racks to cool completely.
