Icing will not form stiff peaks
Help. I'm in the middle of trying to rough ice my Christmas Cake!
For many years I've used Delia's recipe for Royal Icing but found over the last few years I've had problems with getting it into stiff peaks - our family like hard icing. Today seems worse than ever. What am I doing wrong and more importantly what can I do to get it right (or near enough to enable stiff peaks)?
