I have a shell mold too, they would be super easy to make...just melt white and milk or dark chocolate, swirl gently together and pour into the molds. But to take to Mexico...I may just buy the Guylian chocolates that are starting to appear all over in stores for Christmas (and lots of lesser - known chocolate companies put them out as well for cheap). I'm thinking they'll travel much better than a home-made chocolate, but I'm sure it could be done! Either way, I plan to have my mom carry them in her carry-on with a cold pack in her bag...then we'll keep them in our AC'd room. I wouldn't put them in the fridge, as there may be condensation when you take them out and they'll lose their glossy exterior.
So kool... How are these marble chocolate shells made? I have the shell mold and I watched a few videos on youtube on making them with gumpaste but chocolate sounds much more appealing! Has any one made them or do you know where to buy them?
