Today I'd like to propose a family dessert: a crunchy lemon flavored semifreddo prepared by my mother, who in turn received the recipe from a dear friend (thanks Anna for having started all of this!). I enjoy these stories because at each step something is modified, and in the end, the recipe takes on a life of its own. You can serve it as a "tile" directly from the loaf pan, or measure doses with an ice cream spoon, adding additional crumbled meringues at the end.
