Preheat your oven to 350°F (175°C). Do not grease the angel food cake pan.
In a medium bowl, sift the cake flour, ¾ cup (150 g) of the granulated sugar, and salt together. Set aside.
In a large bowl, place the egg whites and use an electric mixer or whisk to beat them until foamy.
Add the cream of tartar and continue to beat until soft peaks form. Gradually add the remaining sugar, about ¼ cup (50 g) at a time, until stiff peaks form.
Mix in the vanilla extract and almond extract (if using).
Gently fold the sifted flour mixture into the egg whites in three parts. Use a rubber spatula to cut through the mixture and fold until just combined. Be careful not to deflate the egg whites.
Pour the batter into the ungreased angel food cake pan. Smooth the top gently with a spatula.
Bake in the preheated oven for 30 to 35 minutes, or until the cake is golden brown and a toothpick inserted in the center comes out clean.
Once baked, invert the pan onto a cooling rack and allow the cake to cool completely in the pan.
Once cool, run a knife around the edges to loosen and carefully remove the cake from the pan.
Serve with sliced fresh strawberries and a dollop of whipped cream if desired.
