Stephanie Alexander is a national icon: an internationally renowned cooking guru, best-selling writer and inspirational founder of a nationwide kitchen-garden scheme for schoolkids. She's also the final arbiter of kitchen disputes in homes all over Australia – resolving disagreements about how to store tomatoes and when to take the sponge out of the oven – as the author of Australia's most famous cookbook, The Cook's Companion. The 2.8-kilogram culinary doorstopper turns 30 this year, and Alexander joins Good Weekend senior writer Amanda Hooton for a chat about restaurants and writing, eating and air-fryers.
