Drain maraschino cherries thoroughly on paper towels; set aside. Put butter and 1/3 cup confectioners' sugar in a large mixing bowl. Beat with an electric mixer on medium speed 3 to 4 minutes, or until well mixed. Stir in almond extract. Add flour and salt; mix well. Stir in pecans. Shape about 2 teaspoons dough around each cherry. Place on an ungreased cookie sheet about 1 inch apart. Bake in a preheated 375-degree oven 12 to 15 minutes, or until set but not brown. Roll in confectioners' sugar while still warm. Let cool. If desired, roll in confectioners' sugar again. Makes 4 dozen.
