Today on Bake, Rachel shows you a recipe for an iced orange cake. This is a deliciously, moist and tangy cake and uses freshly squeezed orange juice in the icing. Rachel visits two American bakers who have brought the wholesome, home cooking of the deep south to the UK. They'll show her how to make an all American apple pie with a twist. And the cookery school students discover how to make a spinach, potato and goat's cheese tart with a perfect savoury, shortcrust pastry.
