1 ½ cups powdered sugar
1 cup cake flour
1 ½ cups large egg whites (about 12)
1 ½ tsp cream of tartar
1 cup granulated sugar
1 ½ tsp vanilla
½ tsp almond extract
¼ tsp salt
Move oven rack to lowest position and preheat to 375°. Mix powdered sugar and flour; set aside. Beat egg whites and cream of tartar on medium speed until foamy. Beat in granulated sugar 2 Tbsp at a time on high speed, adding vanilla, almond extract, and salt with the last of the sugar. Beat until stiff.
Sprinkle powdered sugar mix, ¼ cup at a time, over egg whites and fold in. Pour into ungreased angel food cake pan. Gently cut through batter with a clean knife to break air pockets. Bake 30 to 35 minutes. Immediately turn pan upside down onto bottle, and let cool for about 2 hours.
