A very traditional recipe from SW England - lardy cake is *not* for those on diets! It is a sort of layered dough cake thing with a sticky, crunchy glaze on the bottom. It seems to be similar to Cornish heava cakes. This recipe comes from "Mary Berry's Complete Cookbook" and calls for large amounts of "white vegetable fat". I've always made this with lard (pork fat) purely because of it being called "LARDy cake" Strong white flour is whatever you'd use to make bread with - if I've got it right, it should contain more gluten than ordinary cake flour. Cooking time includes rising times.
