**Preheat oven** to **350°F (175°C)**. Ensure your mixing bowl and beaters are completely grease-free.
In a small bowl, sift together **cake flour** and **¾ cup sugar**. Set aside.
In a large mixing bowl, beat **egg whites, cream of tartar, and salt** on medium speed until soft peaks form.
Gradually add the remaining **¾ cup sugar**, beating until stiff, glossy peaks form.
Gently fold in **vanilla and almond extracts** using a rubber spatula.
Sift the **flour mixture** over the egg whites in **three additions**, gently folding after each addition to keep the batter airy.
Spoon the batter into an **ungreased tube pan**, smoothing the top.
Bake for **35-40 minutes**, until the top is golden and a toothpick inserted comes out clean.
**Invert the pan immediately** and let the cake cool completely upside down (about **1-2 hours**).
Once cooled, run a knife around the edges to release the cake. Slice and serve with **whipped cream and fresh berries**!
