It’s probably pretty hard to carve a seashell design out of fondant or gum paste. That’s probably why First Impressions made these Silicone Shell Molds. Which is probably exactly the way the pros do it. Which is probably one reason why professionally-made cakes look so good.
But one thing that is certain, is that these seashell molds can in no way produce as terrifying a result as the Silicone Baby Mold that First Impressions also makes. Mmm, baby cake!
