Preheat oven to 325 degrees. Line 2 cookie sheets with PARCHMENT.

Mix almond paste and granulated sugar in food processor until smooth.

Add confectioners’ sugar and 2 egg whites; process until smooth.

Whisk remaining 2 egg whites in small bowl.

Place pine nuts on shallow plate.

With lightly floured hands roll dough into 1 inch balls.

Coat balls in egg whites, shaking off excess, then roll in pine nuts, pressing lightly to stick.

Arrange balls on cookie sheets, and flatten slightly to form a 1 1/2 inch round.

Bake 15 to 18 minutes in the preheated oven, or until lightly browned.

Let stand on cookie sheet 1 minute. Transfer to wire rack to cool.
