Ingredients
1 cup butter
1/2 cup confectioners' sugar

1 teaspoon salt
1/4 cup amaretto liqueur
3/4 cup finely chopped almonds (optional)
1/2 cup confectioners' sugar for rolling

Preheat oven to 350 degrees F (175 degrees C).
In a medium bowl, cream together the butter and 1/2 cup confectioners' sugar until smooth. Stir in the flour and salt until well blended, then mix in the amaretto liqueur. Fold in chopped almonds if desired. Roll the dough into walnut sized balls. Place the cookies 2 inches apart onto the cookie sheet.
