· 1 3/4 cups sugar· 1/4 teaspoon salt· 1 cup cake flour, sifted· 12 egg whites (the closer to room temperature the better)· 1/3 cup warm water· 1 teaspoon orange extract, or extract of your choice· 1 1/2 teaspoons cream of tartar
Step 1Preheat oven to 350 degrees F.Step 2In a food processor spin sugar about 2 minutes until it is superfine. Sift half of the sugar with the salt the cake flour, setting the remaining sugar aside.Step 3In a large bowl, use a balloon whisk to thoroughly combine egg whites, water, orange extract, and cream of tartar. After 2 minutes, switch to a hand mixer. Slowly sift the reserved sugar, beating continuously at medium speed. Once you have achieved medium peaks, sift enough of the flour mixture in to dust the top of the foam. Using a spatula fold in gently. Continue until all of the flour mixture is incorporated.Step 4Carefully spoon mixture into an ungreased tube pan. Bake for 35 minutes before checking for doneness with a wooden skewer.
