Preheat oven to 350°F and locate your angel food cake pan. Do not butter or spray or grease the pan in any way.
In a large bowl sift together ¾ cup (150 grams) of granulated sugar and the sifted cake flour.
In the bowl of your stand mixer fitted with the whisk attachment, beat the egg whites until foamy, about 2 minutes.
Add the cream of tartar, lemon juice, vanilla, and almond extract and continue to beat until soft peaks form roughly 2-3 minutes.
Gradually beat in the remaining ¾ cup (150 grams) granulated white sugar, a tablespoon at a time, until glossy stiff peaks form. You may need to scrape down the sides of the bowl.
Remove bowl from stand mixer.
Sift the flour mixture (¼ cup at a time) over the egg whites and using a rubber spatula, gently fold (do not stir) the flour into the egg whites.
Pour the batter into the pan and run a metal spatula or knife through the batter in a zig-zag motion to remove any air pockets. Smooth the top and then bake in the preheated oven for about 40-45 minutes. The cake is done when the cake springs back when gently pressed or there are cracks over the top.
Immediately upon removing from the oven invert the pan and allow the cake to cool for about 1 ½ hours. While the cake is cooling, roast the strawberries.
When completely cool, run an offset spatula or knife around the sides and center tube of the pan to loosen the cake and then remove the cake from the pan.
Next, use the offset spatula (or knife) along the bottom and remove. Set cake on cake stand.
