For Sydney sisters Sammy and Bella, cooking is a family affair. Their grandmother Ursula was a chef in Poland who cooked for many high-profile politicians including former US president Bill Clinton. "She worked as a caterer for all the embassies so whenever there was a diplomatic event or a big political function she was part of the catering team," Sammy says . "She cooked for a lot of influential people, including Bill Clinton, which was the highlight of her career." Bella adds: "Cooking is definitely in our blood. It's been passed on from one generation to the next in our family." Not only have the sisters paired up for the competition but they used to work together in fashion; Sammy, 22, as a buyer and Bella, 27, in marketing . But in a strong indicator of their passion they both quit their jobs to take part in My Kitchen Rules.
