Preheat your oven to 325°F (165°C). Do NOT grease your tube pan.
In a medium bowl, sift the cake flour and ¾ cup of granulated sugar together 3 times.
In a large bowl using an electric mixer, beat egg whites until foamy. Add cream of tartar and salt, then beat until soft peaks form.
Gradually add the remaining ¾ cup sugar, about 2 tablespoons at a time, while continuing to beat. Add vanilla and almond extract, then beat until stiff, glossy peaks form.
Using a large rubber spatula, gently fold the flour-sugar mixture into the egg whites about ¼ cup at a time.
Gently spoon the batter into your ungreased tube pan. Run a knife through the batter to remove any large air pockets.
Bake for 40-45 minutes, until the top springs back when lightly touched and a toothpick inserted comes out clean.
Immediately invert the pan onto a bottle neck or cooling rack with feet. Allow to cool completely, about 1-2 hours.
While the cake cools, mix sliced strawberries with sugar, lemon juice, and zest. Let stand for 30 minutes to 1 hour to create a natural syrup.
In a chilled bowl, beat heavy cream, powdered sugar, and vanilla until soft peaks form.
Once completely cool, run a knife around the edges of the pan to loosen the cake. Remove from the pan and place on a serving plate.
Top with whipped cream and macerated strawberries just before serving.
