It's the final week of MasterChef 2016. All the amateur cooks have just one goal: to lift the coveted MasterChef champion trophy. The final four talented amateur cooks embark on a culinary odyssey to Mexico, where they face a series of challenges they will remember for the rest of their lives. Mexico is home to a cuisine that has remained fundamentally unchanged for thousands of years, and the finalists' journey begins in the country's capital, Mexico City, known for its extraordinary markets, exotic produce and vibrant street food.
