These little cookies — described by one friend as tasting like a cookie within a cookie — are really a mixture between a meringue and a cookie. Hence they've become known at home, where they're immensely popular, as Merookies, and are ideal with a cup of coffee after dinner. They are called "forgotten" as, just like the Forgotten Pudding, they are not baked, but put in a hot oven, which you immediately turn off, leaving the cookies to bake in the fading residual heat overnight. I find it all too easy actually to forget them, and always put a post-it sticker on the oven to remind me they're in there, so I don't burn them to a cinder by preheating the oven to cook something else in it the next day. For US cup measures, use the toggle at the top of the ingredients list.
