Wedding cake toppers are models or art pieces that sit atop the cake. In the US, the most common type of cake topper features a representation of a bride and groom in wedding attire. This custom was dominant in US weddings in the 1950s, where it represented togetherness. Wedding toppers may also be figures that indicate shared hobbies or other passions, if they are used at all. Some are humorous, or may represent the couple's hobby or occupation. In Mexico, the wedding topper and other decorations tell a story about the couple's history.
i used them for a baroque wedding cake i made a few months ago. it was a four-tiered rectangular cake (each stack placed at different angles atop one another) and was covered in fondant painted in gold/red stripes. then i placed the poppies around the corners of the tiers. they weren't as vivid as yours though :( - ill try making them with red gumpaste/fondant next time.
Wedding cake was originally a luxury item, and a sign of celebration and social status. The bigger the cake, the higher the social standing. Wedding cakes in England and early America were traditionally fruit cakes, often topped with marzipan and icing with tiers, Cutting the cake was an important part of the reception. White icing was also a symbol of money and social importance in Victorian times, so a white cake was highly desired. Today, many flavors and configurations are available in addition to the traditional all-white tiered cake.
You should use a recipe specifically designed to be a wedding cake as it will ensure that it is sturdy enough and that it makes the right amount of batter and icing. For a three-tier cake, you need to make three cakes of 12", 9" and 6", as well as a massive amount of icing. Most three-tier cake recipes have a step-by-step schedule for when you will need to bake and assemble each part.
