DirectionsPreheat oven to 350F Line a cookie sheet with parchment paper and set aside.
Using a clean bowl and beaters, beat egg whites with an electric mixer until soft peaks form.
With mixer running, slowly add sugar and beat until whites hold stiff peaks.
Combine next 3 ingredients (egg yolks, vanilla, salt) in another bowl and beat with electric mixer until pale yellow and thickened.
Fold beaten egg whites into yolks until just combined.
Fold in flour.
Transfer to a pastry bag fitted with a 1/2 inch tip.
I think I've also seen a cookie press used to form these.
Pipe mixture into finger shapes 4-5 inches in length, spacing about 2 inches apart.
Sprinkle with additional sugar.
Bake 10-12 minutes until very lightly golden in color.
Alternative for pastry bag: Fill a large sealable plastic storage bag with mixture, squeezing bag to remove all air before sealing.
Using scissors, cut off bottom corner to make a 1/2 inch hole.
