Before I share a really awful photo with you, let me tell you this - it is delicious. I mean, REALLY delicious. That's why I've made it twice. Don't make one and think you'll have a piece later, because there will be none left. I won't give the recipe details here - who could explain it more concisely than Mary? But I urge you all to search out this recipe (the whole book if I were you!) and get baking.
Are you ready for the photo? Prepare yourself.
