The first time I spoke to Kerryman and chef John Relihan was in a field in Dublin while he carefully monitored a breeze block barbecue set-up. It was a balmy August afternoon, with everyone wearing sunglasses and squinting through the aromatic wood smoke that hung over the 2015 Big Grill Festival in Herbert Park. As I interviewed him about his career up to that date – training in Jamie Oliver’s Fifteen restaurant, stints at renowned spots like St John in London and Incanto in San Francisco, and back to London to work at Jamie’s Barbecoa; all by the age of just 29 – John never lost focus on the food, happy to talk to me but always keeping an eagle eye on timings to get the meat just right.
