Silken white chocolate buttercream is an essential icing in any baker's arsenal. This one starts with a base of Swiss meringue, wherein egg whites and sugar are mixed in a bain marie until they reach 140º. They're then whipped to fluffy peaks and flavored accordingly. Use this icing to frost a summery Lemon Curd Layer Cake.
