And for Yossra, the chance to Nigella would have been an emotional one.
"I really started cooking when I moved to Australia and my first inspiration to cook was Nigella Lawson," the Egyptian-born cook told 10Daily.
"She just made me feel… her style is my style of cooking. I love comfort food, I love late night, midnight snacks, I love pasta.
"It was one of my goals, I said, 'if I ever go to MasterChef, I have to stay until I can cook for Nigella Lawson or attend her week' and I just missed it," she admitted.
"It was devastating, to be honest, one of the things that I can’t get over is the fact that I missed Nigella Lawson."
