Mocha-Pistachio Wedding Cake
This cake, with its alternating white and pistachio-flavored layers, was originally created for the wedding of Fraser Lewis and Matthew Edwards. All components of the cake—the cake layers, pastry cream, and buttercream—can and probably should be made at least a day in advance. If you plan to transport the cake, assemble the individual tiers first, giving them their final coat of buttercream, then stack them. Place the bottom tier (still on its cardboard round) on a wooden cake board at least four inches wider than the tier. To keep the cake from slipping, line the wooden board with a rubberized nonslip mat, or secure the cardboard round to the board with hot glue. If possible, pipe the decorations once you have reached your location; wait to garnish the cake with the flowers until it is positioned on the serving table.
