The national dish of Peru, and a popular street-eat all along the coast (and around inland waters, too), ceviche is incredibly easy to make. Prepare your fish in one bowl, the marinating ingredients in another, then once you mix the two together it takes just 10 minutes to ‘cook’ the fish to perfection.
Place the diced fish in a bowl. Sprinkle over the salt, stirring well to mix. Leave to rest for 5 minutes. In a separate bowl or jug, mix together the lime juice, onion, chillies, coriander and a good grind of black pepper. About 10 minutes before you want to serve, simply pour the marinade over the fish, stir well, and leave to rest. To serve, spoon into small cups or pile on a plate and drizzle over a little olive oil.
