Hong Kong Style Egg Roll (Swiss Roll)

The scent of these light and airy egg rolls always transports me back to my childhood. I remember sneaking into my grandmother’s kitchen, the rhythmic whir of her stand mixer a comforting soundtrack to my afternoons. She’d let me “help” by carefully sprinkling the sugared towel, a task I took with utmost seriousness, and then, the ultimate reward: a warm slice of the freshly rolled cake, the creamy filling a sweet, blissful cloud. These weren’t just desserts; they were edible hugs, woven with love and tradition.

Ingredients

3 egg yolks
2 teaspoons sugar
3 tablespoons cake flour
2 teaspoons cornstarch
2 tablespoons oil
4 teaspoons milk
1/4 teaspoon baking powder
3 egg whites
7 teaspoons sugar

Filling:

Firm whipping cream

Equipment Needed

Electric mixer
Non-metal mixing bowl
8-inch baking pan
Parchment paper
Clean towel
Another baking tray

Instructions

Preheat your oven to 375°F (190°C). Ensure the oven rack is positioned in the center.
In a non-metal mixing bowl, use an electric mixer at medium speed to beat the egg yolks.
Gradually add the 2 teaspoons of sugar to the yolks, continuing to beat until well combined.
Blend in the 2 tablespoons of oil and 4 teaspoons of milk. Mix until a pale yellow batter forms. The mixture should lighten in color and become slightly thicker.
Sift together the 3 tablespoons of cake flour, 2 teaspoons of cornstarch, and 1/4 teaspoon of baking powder. This ensures there are no lumps and the dry ingredients are evenly distributed.
Add the sifted dry ingredients to the egg yolk mixture and mix gently until just combined. Be careful not to overmix; a few streaks of flour are okay at this stage.
In a separate bowl, beat the egg whites with an electric mixer at high speed.
Gradually add the 7 teaspoons of sugar to the egg whites while continuing to beat until you achieve soft peaks. The peaks should hold their shape but gently droop at the tip.
Spoon half of the egg white batter into the pale yellow cake batter. Fold in slowly and gently. Folding helps to incorporate the egg whites without deflating them.
Add the remaining egg white mixture to the batter. Again, fold gently until everything is fully combined. Be extra careful not to deflate the batter. This step is crucial for achieving a light and airy cake.
Line an 8-inch baking pan with parchment paper. Make sure the parchment paper extends slightly beyond the edges of the pan to make it easier to remove the cake later.
Pour the batter into the prepared pan and spread it evenly to all sides. This ensures the cake bakes evenly.
Quickly bake it in the preheated oven for 10-15 minutes, or until the top turns golden brownish. Keep a close eye on the cake, as it can burn easily. The cake is done when a toothpick inserted into the center comes out clean.
While the cake is baking, dust a clean towel generously with sugar. This will prevent the cake from sticking to the towel during the rolling process.
Once the cake is removed from the oven, place it (with the parchment paper) on another tray.
Cover the cake with the sugared towel and put another tray on top of the cake. This helps to trap the moisture and keep the cake soft and pliable.
When the cake is warm, remove the parchment paper from the cake. Be gentle to avoid tearing the cake.
Roll the cake tightly with the towel and leave it to cool completely. This step is important to create the signature swirl of the Swiss roll.
Once the cake has cooled completely, unroll it gently.
Spread the firm whipping cream evenly on the inside of the cake. Make sure to leave a small border at the edge to prevent the filling from squeezing out when you roll it up.
Roll the cake tightly again, this time without the towel.
Chill in the refrigerator for at least 15 minutes to allow the filling to set and the cake to firm up. This makes it easier to slice.

Expert Tips & Tricks

Room temperature ingredients: Make sure your eggs are at room temperature. They will whip up more easily and create a lighter, airier batter.
Don’t overmix: Overmixing the batter can lead to a tough cake. Mix until just combined, and fold the egg whites in gently.
Parchment paper is your friend: Lining the pan with parchment paper makes it much easier to remove the cake without tearing it.
Sugared towel: The sugared towel is crucial for preventing the cake from sticking and cracking during the rolling process. Don’t skip this step!
Cooling is key: Make sure the cake is completely cool before filling it. Otherwise, the filling will melt.
For extra flavour: Add a teaspoon of vanilla extract to the whipped cream or the cake batter for an extra layer of flavour.
Troubleshooting cracks: If your cake cracks when you roll it, don’t worry! You can cover the cracks with more whipped cream or dust the roll with powdered sugar.

Serving & Storage Suggestions

Serve the Hong Kong Style Egg Roll chilled, sliced into 1-inch thick pieces. A light dusting of powdered sugar adds an elegant touch. It’s delicious on its own or served with a cup of tea or coffee.

Room Temperature: This cake is best stored in the refrigerator. It can sit at room temperature for a short period (1-2 hours), but the whipped cream filling will soften quickly.
Refrigerator: Store the egg roll in an airtight container in the refrigerator for up to 3 days.
Freezer: While not ideal, you can freeze the egg roll. Wrap it tightly in plastic wrap and then in foil. Freeze for up to 1 month. Thaw in the refrigerator overnight before serving. Be aware that the texture of the cake and filling may change slightly after freezing.

Variations & Substitutions

Fruit Filling: Instead of whipped cream, fill the roll with a layer of your favourite fruit jam or fresh berries.
Dairy-Free Option: Substitute the milk with almond milk or soy milk. Use a dairy-free whipping cream alternative.
Citrus Zest: Add the zest of one lemon or orange to the cake batter for a bright and refreshing flavour.
Coffee Flavour: Dissolve a teaspoon of instant coffee in a tablespoon of hot water and add it to the cake batter for a coffee-infused roll.

FAQs (Frequently Asked Questions)

Q: Why is it important to fold in the egg whites gently?
A: Folding gently prevents the batter from deflating, which is crucial for achieving a light and airy cake texture. Overmixing can result in a dense and tough cake.

Q: Can I use regular flour instead of cake flour?
A: While you can, cake flour has a lower protein content, which results in a more tender and delicate crumb. If you must use regular flour, substitute 2 tablespoons of flour with 2 tablespoons of cornstarch for every cup of flour used.

Q: My cake cracked when I rolled it. What did I do wrong?
A: Cracking can occur if the cake is too dry or if it wasn’t rolled tightly enough while warm. Make sure to use the sugared towel to keep the cake moist and roll it firmly while it’s still pliable.

Q: Can I make this ahead of time?
A: Yes, you can bake the cake layer a day in advance. Wrap it tightly in plastic wrap and store it at room temperature. Fill and roll the cake on the day you plan to serve it.

Q: What is the best way to slice the egg roll?
A: Use a sharp, serrated knife. For clean slices, chill the roll thoroughly and wipe the knife clean between each cut.
