Aldo Zilli makes a guest appearance on MasterChef series 12, as the semi-finals continue.
Forty amateur cooks have been whittled down and now only the most promising seven remain in the competition, all fighting for a place in Finals Week.
In this programme they have to pull out all the stops as they are tasked with the daunting challenge of cooking for some of the world's most celebrated restaurateurs, including Aldo Zilli. Travelling to London's fashionable Chelsea, the amateur chefs are thrown into service at the culinary landmark Bluebird where they take full control of its kitchens.
John Torode oversees the kitchen, as the amateurs face a high pressured lunchtime service. The diners are all restaurateurs who are at the forefront of dining trends and have paved the way for culinary excellence, so their expectations are sky high.
The contestants must each serve one dish of their own creation on the specially designed menu. Under the watchful eye of John Torode, the amateurs will be challenged like never before to deliver dishes of an exceptional level, because the two chefs who cook the most popular dishes will be exempt from the next cook-off.
Back at the MasterChef kitchen, the remaining five chefs have to cook against each other in a bid to stay in the competition. It's high drama as the amateurs push themselves to the limit to impress judges John Torode and Gregg Wallace. Who can impress enough to make it through to the final four and keep their dream alive of winning MasterChef 2016?
