After baking the sponge cake slab 15 minutes while it is still soft, apply a layer of whipped cream on top, then spread it evenly.
Cut the flan in half, use a spatula knife then transfer it into the sheet cake with fresh cream on top, place on the top of sponge sheet.
With a bag of fresh cream then pipe along the sides of flan to prevents forming holes when rolling
With a paper underneath, start rolling from the top, slowly and carefully to make sure the flan not pull apart from the sheet cake. Then use the aluminium foil to wrap and secure the shape (can use sticky tape if you wish), leave it the fridge for at least 3 hours (I prefer overnight)
Un-wrap it then spread a thin layer of fresh cream on top, sprinkle with caramelized almond flake on top, then it is ready to eat.
To cut or slice, I use a serrated edge knife or called bread knife, dip a knife into a hot water and wipe it for every slice cut to make sure you will have a clean and smooth cut, looks attractive.
