The humble donut has developed a bit of attitude lately. It’s not just Mexican churros and Italian zeppole that are turning up on the cafe tables and menus of some of the world’s premier establishments. Croissant- donuts, lemon meringue donuts and those almost-good-for-you, paleo baked donuts are taking the world by storm. These hot, sticky delicacies are not hard to recreate at home when you know how (no, you don’t need a deep-fryer!).
