This Earl Grey chiffon cake recipe is a sophisticated twist on the classic chiffon cake. Made with the Thermomix, it is light, fluffy, and has a subtle Earl Grey flavor. The cake is made with a combination of cake flour, sugar, baking powder, salt, vegetable oil, egg yolks, water, and Earl Grey tea leaves. The egg whites are whipped separately and then folded into the batter to give it its signature airy texture. This cake is perfect for serving with a dollop of whipped cream and a sprinkle of tea leaves.
