Emma set to plate up against Lynton and Samira in Sunday's MasterChef finale MasterChef final three Emma Dean, Lynton Tapp and Samira El Khafir Source: Supplied SAMIRA El Khafir, Emma Dean, and Lynton Tapp are set to fight it out in this Sunday's finale of MasterChef Australia. The trio made the cut after the shock elimination of Rishi Desai from the Channel 10 cooking show. The 35-year-old public servant had been expected to sail through the culinary duel after winning the previous episode's Atlantic restaurant service challenge. That gave Rishi the power to determine the protein, cuisine and the person he was going to cook off against. Rishi took on Emma and stumbled from the start. His mussels in round one were overcooked and unappetising. Lynton won round two against Samira, the pair challenged to cook a middle-eastern dish using kangaroo. That left Rishi and Samira to battle it out in a third round, using beef eye fillet for a French-style dish. Rishi made a fatal flaw in failing to poach his leeks. Samira triumphed despite a weird celeriac puree with coriander. A devastated Rishi says he still plans to open a top-notch restaurant serving modern Indian cuisine. Rishi Desai was devastated to be knocked out of MasterChef. Samira says that making Sunday's finale is reward after a torturous battle with post natal depression. "I suffered from post natal depression for one year before this competition," the 28-year-old mother of two said. I was lost and forgot who I was and food and cooking helped me out of my depression. (MasterChef shows) you can move on in life and do amazing things. Making the finale has given Emma, a former transport planner, the confidence to pursue the dream of owning a restaurant. Lynton has helped his sister Emily through her rehabilitation after she became a paraplegic in a horse-riding accident. His parents recently lost their farm. "I came here at the start of the competition for my family," he says. As I've progressed and learnt more about myself and my cooking, I've realised this is the way I can turn my life around. The finale will be split into three rounds - an Invention Test, a Service Challenge, and a Pressure Test. Sunday's winner will receive a $100,000 cash prize, a car, a cookbook deal and work opportunities at some of Australia's best restaurants. The MasterChef Australia Season 5 finale will air on Ten this Sunday at 7.30pm.
