SIMPLE SUGAR SYRUP
Add the water and granulated sugar into a medium-size pot and heat over medium heat.
Bring the mixture to a boil, stirring occasionally, then simmer for 4 minutes without stirring the syrup.
Remove the pot from the heat, and allow it to cool to room temperature for at least 20 minutes.
Keep stored in the refrigerator in an airtight container or mason jar until ready to use.
PORTUGUESE ORANGE ROLL CAKE
Preheat the oven to 180°C (350°F), and line the bottom of an 11 x 7-inch rectangular baking pan with parchment paper, then spray with the pan and release the bottom and sides.
Traditional Method: Zest the oranges and keep orange zest aside. Then juice the oranges and reserve.
Combine the flour, salt, sugar, and banking powder into a medium-size bowl and whisk together.
Mix the eggs, orange zest, and orange juice in a bowl using a whisk. Then add the melted butter and whisk for 1 minute.
Add the flour mixture into the egg mixture and mix together until well combined. The batter will be very liquidy.
Blender Method: Combine all the ingredients into the blender and blend on low for about 45-60 seconds.
Pour the mixture into the baking pan and bake for 20-25 minutes. To test if the cake is ready, insert a toothpick, if it comes out clean, then the cake is baked.
In the meantime, place a sheet of parchment or cloth onto a working surface and sprinkle with sugar.
Remove the cake from the oven and flip it onto the sugar-coated sheet or cloth. Then remove the parchment paper attached to the cake.
Carefully curl the cake into a log starting from the side closest to you using the parchment paper as a guide.
Decorate the cake with our simple glaze and garnish with some zest pieces or orange slices.
Enjoy!
