Mix the ingredients: take the granulated sugar and mix it with meringue powder and water. Don’t add too much water: you don’t want a paste form. Thoroughly mix everything for a few minutes until you get a consistency like sand. Now, take a small amount of mixture and form an indentation with your thumb. If the clump doesn’t fall apart, it means that the mixture is ready and it’s time to go to the next step: molding.
Mold the Mixture: Take the sugar skull mold and pack it tightly with the mixture. Use a sharp metal object like a knife or scraper to remove the excessive mixture. Now, take a cardboard plate or panel over the mold, gently flip it over and place it on a flat surface. Reveal your sugar skull by carefully removing the mold.
Let it dry: Leave the sugar skull in an airy place and let it dry for at least 5 to 6 hours. After getting it dry your sugar skull is ready. You can decorate it with colorful icing according to your own design sensibilities.
