- 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.
