Fluffy and delicious, REID safe, GFCF Angel Food cake for any occasion!
Separate the egg whites and let them sit at room temperature for about half an hour.
Preheat the oven to 350. In a bowl sift and combine the flour, vanilla (if using dry, ground kind) and powdered sugar together. Set aside.
Grind the granulated sugar and calendula petals slightly, about 5-7 pulses. No need to turn it into powdered sugar, just a little finer than it is normally. Set aside.
Beat the egg whites on high until starting to foam then add the salt and the vanilla (if using liquid vanilla) and continue whipping at high speed.
Add the granulated sugar slowly, about 1 Tbsp at a time to the egg whites while they are whipping. Continue whipping until stiff peaks form.
Slowly fold in the dry ingredients 1/3 at a time with a spatula. (fold in the extra ingredients for Pumpkin version in this step). Do this carefully and slowly, for you don't want to deflate the egg whites. (very important!)
Pour the batter into an ungreased* 10-inch round pan.
Bake at 350 for about 35-40 minutes until lightly golden. Take it out of the oven and IMMEDIATELY invert pan onto a cooling rack or a jar, so it will cool upside down(very important step, otherwise it will deflate)
Cool completely for 3 hours, then run a knife along the edges of the pan and carefully plate the cake. Enjoy!
