Cork's Holy Smoke head chef tells us how to spark up and cook the perfect BBQ

One of the stars at the just-passed Ballymaloe Litfest was Argentinian chef Francis Mallmann whose restaurant, Francis Mallmann 1884, in Mendoza, Argentina, has featured in that elite club, The World’s Top 50 Restaurants.
However, what caught the imagination of so many festivalgoers was the same thing that made an episode of the Netflix series, Chef’s Table, featuring Mallmann so especially compelling —he cooks with fire and, before the solid-fuel Aga owners club harrumph their parity, let it be noted we are talking about cooking over naked flame and his book, Seven Fires: Grilling the Argentine Way, has made many waves on a global scale.
