This newspaper clipping has been floating around for a while. I am unable to find the original source, but the recipe seems to have appeared elsewhere in June of 1966. A version was published in the Alton Evening Telegraph.
Karloff was an immensely likable actor. He was initially cast to frightening effect in those famous mute rolls: Frankenstein’s monster, the servant Morgan in The Old Dark House. But when he spoke he could not help but exude charm. He had a gentle voice and a rather endearing lisp. I have always liked his detective characters (Mr Wong and Colonel March of Scotland Yard) as much as his monsters.
