Make meringue.1. Whip egg whites until they look like stiff peaks, very fluffy and stiff. 2. Add about half of the sugar when the meringue looks very bubbly.3. Add the remaining sugar when the meringue looks foamier.4. Mix it at low speed at the end to make the bubbles smaller. It leads to a more silky, fluffier cake texture. Use it right away while the condition is the best!Tip💡Ensure any liquids and oil (including yolks) are mixed in the egg white bowl and a whisk. They prevent the egg whites from whipping up well.
4.6 oz Egg white, 1.7 oz Granulated sugar
Add the meringue to the pumpkin mixture.1. Add ⅓ - ½ of the meringue into the pumpkin mixture and fold it with a whisk until 75 - 80% is mixed, add the rest of the meringue.

Switch to a rubber spatula and clean the bottom sides of a bowl until evenly blended.Tip💡The French meringue separates very quickly in a short time. Use it right away while the condition is the best and re-whip it with a whisk attachment if it starts separating.
Bake the cake.1. Pour the cake batter into the chiffon cake pan (The bottom: 15 cm | 6 inches) and swirl the batter with a toothpick to eliminate bigger air bubbles.2.
