The four remaining celebrities in heat four face three more culinary challenges as they compete for a place in the last quarter-final.Their first challenge is a Knowledge and Skills Test, where the celebrities have the terrifying task of facing judges John Torode and Gregg Wallace one on one. They must demonstrate their ability to make sweet and sour prawn balls in just 20 minutes.Next, the celebrities are pushed to their limits. Up until this point in the competition, they have been cooking food as they would at home, but to show them what restaurant standard cooking is all about, John and Gregg invite in a professional chef. Anna Haugh, owner of the restaurant Myrtle in London, challenges each of the four celebrities to cook a recipe from her menu, which champions Irish produce.Then it's crunch time, with just one more chance to earn a place in the quarter-final. The brief is to recreate their favourite takeaway. With just one hour to cook, and only three quarter-final places up for grabs, the celebrities give it their all in a final attempt to prove themselves to the judges. At the end of this test, one of them will be going home.

Three celebrities return for the last quarter-final. They must cook a faultless two-course meal that will be judged not only by John and Gregg but also by three Celebrity MasterChef champions: Kadeena Cox (2021), Greg Rutherford (2019) and Angellica Bell (2017).Only the best two contestants can move one step closer to winning the title of Celebrity MasterChef 2022. For the one who doesn't cut the mustard, the journey ends here.

Celebrity MasterChef continues this week, and after four weeks of intense competition, the best eight cooks from the heats have made it through to the semi-finals. Starting tonight, the remaining hopefuls are battling for their place in the final week with a test to their teamwork.The celebrities travel to North Weald Airfield, home to the Essex and Herts Air Ambulance, to face their toughest challenge yet. Cooking in tents and faced with unfamiliar equipment, the semi-finalists must cook up a feast for 70 pilots, medics and support staff who work for this life-saving organisation.Split into two teams, it's a race against the clock as the celebrities must each design and create four mouthwatering dishes (a meat, fish and vegetarian dish, and a dessert) in just three hours. Next, it's back to the MasterChef kitchen, where they face an Invention Test using the leftovers from the previous challenge, to stay in the competition.Everything rides on the success of their dish because at the end of this challenge, one celebrity will be going home, and their dream of being Celebrity MasterChef Champion 2022 will be over.
