How to Make It
Beat egg whites and cream of tartar at high speed with an electric mixer 1 minute or until soft peaks form. Gradually add sugar to egg white mixture, beating 2 1/2 minutes or until stiff peaks form and sugar dissolves. Gently fold in chocolate morsels.
Drop mixture by teaspoonfuls onto 2 lightly greased parchment paper-lined cookie sheets.
Place in 400° oven, and turn oven off. Leave in oven overnight or 8 hours.
