I saw the idea for making little caldrons using these little salsa bowls you can get at the dollar store (2 for a buck) at dawnypoo and I decided to give it a go. I put a cupcake I dyed green at the bottom of the bowl and added a second one with crumbs around the side to fill the bowl a little further.
I squiggled icing and then just added a bunch of gum eyeballs and gummy 'stuff' I got in candy bins at the store.
Gummy worms and I go way back. Easy cupcake. No icing technique required, just put some in a ziplock and let it flow.
