Preheat your oven to 350°F (175°C).
Sift the cake flour and half of the sugar together in a bowl.
In a large mixing bowl, beat the egg whites until foamy.
Add cream of tartar and salt, then continue beating until soft peaks form.
Gradually add the remaining sugar, beating until stiff peaks form.
Gently fold in the vanilla and almond extracts.
Carefully sift the flour mixture over the egg whites in batches and fold gently.
Pour the batter into an ungreased tube pan.
Bake for 35-40 minutes or until golden and springs back when touched.
Invert the pan and let the cake cool completely before removing it.
