To finish assembling the cake, remove from the refrigerator and place your prepared merengue on top. You can apply the merengue using an icing bag for a more decorated look, or simply use a spoon. Pre-heat your oven to ‘broil’ and when hot, bake for 3-5 minutes or until the merengue has begun to turn golden-brown. Make sure to watch you cake carefully, as merengue burns easily. Let fully cool and refrigerate before serving.
