LONDON – Prince Harry and Meghan Markle’s wedding cake has taken six bakers five days to prepare and breaks with tradition, according to its designer Claire Ptak. Harry, Queen Elizabeth’s grandson, and US actress Markle will tie the knot on Saturday (May 19) in Windsor Castle’s 15th-century St George’s Chapel. Ptak said her design was more of an “installation” than a typical wedding cake, but offered few details.
