Gareth Whitton was the head pastry chef at Dinner By Heston Blumenthal and former pastry chef at Kate Reid's Lune before launching Tarts Anon as an online side hustle during the Covid lockdowns. It soon snowballed into a hit retail store in Melbourne's Cremorne, an appearance on MasterChef Australia and a stunning run on the smash hit spin-off Dessert Masters. Gareth does the baking while his partner Catherine – a speech pathologist with a handy knack for dessert logistics – oversees everything else.
