It’s an honour to feature two recipes from leading US chef Grant Achatz. His Chicago restaurant Alinea is at the forefront of modern cuisine, largely because Grant never stops asking ‘why?’ He’s the ultimate culinary provocateur, questioning every aspect of dining. Why do we need to eat from plates? Why can’t food float? Can I make a stew that’s ice cold and boiling at the same time? His endless questing has led to some of the most mind-bending meals ever served.
