I want to learn to use the rice crispy treats and do sculpting the large items for the cakes and supposedly the other confections possible. Can you teach me how do I sculpt with the rice krispies treats? All I know is that I have to pour the hot rice crispy treat batter into a respective tall pan so that I can start with a thick block to be able to make it to allow easy carving. And then I have to let the treats to cool down. What am I supposed to proceed from here?
