My mom made these for us as kids and we loved them (but hated that we couldn't eat them)
My kids and their cousins made these last year and we had so much fun.
This year I had to hunt for the recipe again, so here it is.
The molds can be found in hobby or craft stores.
3.5 c. white sugar
1/2 c. powdered sugar
1 egg white
Whisk egg white in medium bowl until frothy. If coloring is desired, add at this time. As large amounts of sugar will be added, make colors more intense as the sugar will dilute the color.
Whisk sugars together in another bowl until well mixed. Add to egg white mixture.
Continue to stir as sugar will gradually begin to dampen. Mixture should be moist like damp sand, and should clump if squeezed in a hand.
Firmly pack sugar into egg mold making sure there are no air pockets or cracks.
Using knife or spatula, level top and remove excess sugar.
Place a plate or cookie sheet over molds, and invert.
Remove egg mold, and allow to dry for 1-2 hours at room temperature or place in 200* oven for 25 - 30 minutes. If oven method is used, allow to cool.
Using royal icing as glue, add colored coconut for grass, and candies and small animal figurines.
After completing inner scene, using royal icing, glue sides together and decorate as desired.
