BLEACHED CAKE FLOUR:Bleached cake flour helps achieve a light and tender texture while ensuring the cake rises evenly and holds its shape. Unlike all-purpose flour, bleached cake flour has a lower protein content and finer granulation, which is ideal for creating a softer crumb in delicate cakes like angel food cake.
GRANULATED SUGAR:When mixed with the egg whites, sugar creates a smooth and stable foam, contributing to the cake’s light and fluffy texture. Additionally, sugar dissolves in the egg whites, creating a thicker mixture that helps hold air bubbles. These bubbles are essential for leavening, allowing the cake to rise evenly and giving it its characteristic structure. While sweetness is its primary function, granulated sugar also enhances the overall flavor profile of the cake.
EGG WHITES: Egg whites are essential in angel food cake, as they provide structure and help the cake rise without using baking powder, baking soda, butter, or oil. When whipped to medium peaks and gently folded into the batter, these whites create a network of air bubbles. During baking, these bubbles expand, resulting in a wonderfully light and airy texture. Eggs are easier to separate when cold but whip up faster and with more volume at room temperature. Make sure there’s no presence of yolk in your egg whites, as fat inhibits the whites from whipping.
CREAM OF TARTAR: Cream of tartar, an acidic salt, is added to stabilize the egg whites and lower the pH, creating a finer grain, making the cake more tender, and keeping it from shrinking.
KOSHER SALT: Kosher salt is a pure, additive-free salt that dissolves readily and has a crisp, clean taste. It is also flaked rather than granulated, allowing for more even distribution when being whipped into the cake batter.
VANILLA: A cake without vanilla extract lacks a beautiful depth of flavor. Vanilla also adds a lovely aroma to the Vanilla Chantilly Cream in the form of vanilla bean paste.
DUTCH PROCESS COCOA POWDER: Dutch process cocoa powder is treated with an alkaline solution of potassium carbonate to make it milder and less acidic in flavor and darker in color. For the Chocolate Angel Food Cake recipe, we love Dutch process cocoa because it’s slightly less astringent in flavor than natural cocoa powder, so it makes an intense but not bitter-tasting cake.
