Critical Mass Catering

In a nod to the British royal wedding, we are super-sizing the Food Chain this week as we explore cooking on a grand scale. Emily Thomas visits a Sikh temple to see how volunteers serve up to a thousand free meals per day without even breaking a sweat. A professional caterer breaks down the economics of mass catering for us. Plus, a foodie chemist gives us his take on mass cooking on a molecular level. And we may or may not be speaking to the man in charge of Prince Harry and Meghan Markle’s wedding menu. (Picture: Quirky and colourful tiered cake Credit: Getty Images)
