I thought if I buttered the inside of the shell, it would not stick once the cake was cooked then I could just break the shell and remove the cake without problem.
Momoreg thanks for the muffin tin idea, I hadn't thought of that. Would be a lot more stable then proping them on a ball of aluminium foil.
Wendy, not to worry about complains I'm just doing it for my family. Of course I'll try it out first. I'll check out Martha's recipe.
If it doesn't work, I'll make chocolate tartelettes and with a small coconut nest on top with a mini candy eggs....
Thanks for your help.
