This cake is ALL edible! I made the "Talavera Tiles" out of fondant, cutting individual 2" x 2" tiles, shaped the corner tiles and allowed all of them to dry completely. They were then hand painted with gel color diluted with vodka (this evaporates and allows the gel color to dry), allowing each color to dry before painting the next color. The envelope and birthday card were also made out of fondant, with the same painting technique. The Calla Lilies were made out of Gum Paste, and "dry-painted" with luster dust and then quickly steamed over a pot of boiling water to set the colors. Buttercream icing was used to cover all of the cakes, and also as "grout" for the tiles. The tile covered "table" and the flower vase were chocolate cake with a hint of cinnamon, to keep with the Mexican "flavor" of this cake theme. Happy Birthday Susie!
