Peruvian Kingfish Ceviche with Tiger's Milk chaser

The intense spiciness of the fish is balanced by the gentle sweet potato. A vodka chaser is not for the faint hearted - and you can omit it if you like. Miguel learnt this recipe from Diego Muñoz, head chef of Astrid y Gaston, a restaurant in Lima, Peru that's ranked as one of the best in the world.
