For the Pineapple Topping:

2 tablespoons sugar
1 tablespoon cornstarch
2 tablespoons flaked coconut

Equipment Needed

15 x 10 inch jelly roll pan
Medium mixing bowls
Large mixing bowl
Electric mixer
Small saucepan
Flour sack towel
Rubber spatula

Instructions

Prepare the Pineapple: Begin by draining both cans of crushed pineapple, ensuring you reserve 3/4 cup of the juice and 1/2 cup of the pineapple for the topping. Set these aside for later use.
Make the Pineapple Base: In a medium mixing bowl, combine the remaining drained pineapple (not the reserved portion) with the brown sugar, coconut, nuts, 1 teaspoon of vanilla extract, cinnamon, ginger, and clove. Mix well to ensure all ingredients are evenly distributed.
Prepare the Pan: Spread the pineapple mixture evenly across the bottom of a 15 x 10 inch jelly roll pan. This will form the flavorful base of your cake roll. Set the pan aside.
Beat the Egg Whites: In a medium mixing bowl, using an electric mixer, beat the egg whites until soft peaks form. This process incorporates air into the whites, creating a light and airy texture that’s crucial for a tender cake.
Sweeten the Egg Whites: Gradually add 1/3 cup of the sugar to the egg whites, continuing to beat until stiff but not dry peaks form. Be careful not to overbeat, as this can make the egg whites grainy. Set the bowl of beaten egg whites aside.
Beat the Egg Yolks: In a large mixing bowl, beat the egg yolks until they become thick and pale yellow. This step is essential for creating a rich and flavorful base for the cake batter.
Flavor the Egg Yolks: Gradually add 1/3 cup of the sugar and the remaining 1/2 teaspoon of vanilla extract to the beaten egg yolks. Beat until the mixture is well combined and smooth.
Combine Egg Whites and Yolks: Gently fold the beaten egg whites into the egg yolk mixture. It’s crucial to be gentle during this process to avoid deflating the egg whites, which would result in a dense cake.
Sift Dry Ingredients: Sift together the flour, baking powder, and salt. Sifting ensures that the dry ingredients are evenly distributed and prevents lumps, resulting in a smoother cake batter.
Incorporate Dry Ingredients: Gently fold the sifted flour mixture into the egg mixture. Again, be gentle to maintain the airiness of the batter.
Spread the Batter: Spread the cake batter evenly over the pineapple mixture in the prepared jelly roll pan. Ensure the batter covers the entire surface to create a uniform cake layer.
Bake the Cake: Bake in an oven preheated to 375 degrees Fahrenheit (190 degrees Celsius) for 20-25 minutes. The cake is done when a toothpick inserted into the center comes out clean.
Prepare to Roll: Loosen the cake around the edges of the pan. Invert the cake onto a flour sack towel that has been generously sprinkled with powdered sugar. Let the cake stand for 3-4 minutes. The powdered sugar will prevent the cake from sticking to the towel.
Roll the Cake: Carefully roll the cake up in jelly roll fashion, using the towel to guide you. This process is best done while the cake is still warm, as it’s more pliable and less likely to crack. Let the rolled cake cool completely.
Make the Pineapple Topping: While the cake is cooling, prepare the pineapple topping. In a small saucepan, combine the reserved pineapple juice, sugar, and cornstarch. Mix well to ensure the cornstarch is fully dissolved, preventing lumps.
Cook the Topping: Cook the mixture over medium heat, stirring constantly, until it becomes clear and thickened. This usually takes a few minutes. The cornstarch acts as a thickening agent, creating a glossy and flavorful sauce.
Add Pineapple and Cool: Remove the saucepan from the heat and stir in the reserved crushed pineapple. Let the topping cool completely.
Assemble the Cake Roll: Once the cake roll and the pineapple topping are both completely cool, carefully unroll the cake.
Garnish: Spread the cooled pineapple topping evenly over the surface of the unrolled cake. Then, sprinkle the top with flaked coconut.
Final Roll: Carefully re-roll the cake.

Expert Tips & Tricks

Prevent Cracking: To prevent the cake from cracking when rolling, make sure to roll it while it’s still warm and pliable. Using a towel sprinkled with powdered sugar helps prevent sticking and tearing.
Even Baking: Ensure even baking by rotating the pan halfway through the baking time. This helps to distribute heat evenly and prevents the cake from browning unevenly.
Moist Cake: For an extra moist cake, you can lightly brush the cake with pineapple juice after unrolling it.
Nuts Variations: Feel free to experiment with different types of nuts in the cake base. Macadamia nuts or pecans would be delicious additions.
Make Ahead: The cake roll can be made a day ahead and stored in the refrigerator. Just wait to add the topping until just before serving.

Serving & Storage Suggestions

To serve, slice the cake roll into individual servings and arrange them attractively on a plate. You can garnish with extra coconut flakes or a sprig of mint for visual appeal. Leftovers should be stored in an airtight container in the refrigerator. It will keep for up to 3 days. The cake roll is best served chilled. Freezing is not recommended, as the topping may become watery upon thawing.

FAQs (Frequently Asked Questions)

Q: Why is it important to drain the pineapple well?
A: Draining the pineapple well prevents the cake from becoming soggy and ensures a better texture. Too much liquid can also interfere with the cake’s ability to rise properly.

Q: Can I use fresh pineapple instead of canned?
A: Yes, you can use fresh pineapple, but be sure to cook it down slightly to remove excess moisture. Canned pineapple is often more convenient due to its consistent moisture content.

Q: How do I prevent the cake from sticking to the towel when rolling?
A: Generously sprinkle the towel with powdered sugar before inverting the cake. This creates a barrier and prevents the cake from sticking.

Q: My cake cracked when I rolled it. What did I do wrong?
A: Cracking usually happens when the cake cools too much before rolling. Try rolling it while it’s still warm and pliable. You can also try lightly scoring the surface of the cake before rolling to help it bend more easily.

Q: Can I make the pineapple topping ahead of time?
A: Yes, you can make the pineapple topping a day ahead of time and store it in the refrigerator. Just be sure to let it come to room temperature before spreading it on the cake.
