I've been asked to make one for an upcoming baby shower. I think I'm going to have to make a 10" cake, but still toying with 8 vs 10. Anyway, the customer wants a rather large pea pod. I'm thinking it's best to make this out of RKT because it's so hard to carve a sphere out of cake, and I don't want to make a giant ball of gumpaste. What have others used?
I used modeling chocolate and covered w/ fondant. You can check in my pix. It was a 9x13, so the pod wasn't really, really big.
I don't know how big you are going, but maybe you could use a cake ball......just mash up your scraps from carving the pod or the wilton half ball pan?
I used the Wilton ball pan (3 halves) and stacked those on a 12"x18" half sheet pan that I cut in half lengthwise and stacked on itself... so I ended up with roughly a 6"wide x18" long pea pod. That equals ALOT of cake and it was heavy! But it ended up being one of my easier cakes to construct. HTH
