Whip the three egg whites that remained from the separated eggs with a pinch of cream of tartar until blended and soft peaks form.
Then add 1 1/2 tablespoon sugar. Beat until the peek are stiff.
Use a piping bag with a star tip and pipe onto pies.
Place meringue in a piping bag fitted with a star tip, I use a 2D tip.
