Combine first 7 ingredients, stirring with a wire whisk; set aside.
Combine sugar, flour, and salt in a large bowl. Gradually add the milk mixture, stirring well (batter will be thin).
Beat egg whites (at room temperature) at high speed of a mixer until stiff peaks form. Gently stir one-fourth of egg whites into batter; gently fold in remaining egg whites.
