Ishrat deserved to stay, but unfortunately it was her bad day.
According to judges Sachin's dish was perfect. But it would have been nicer if judges had waited till all the dishes were tasted. To me, Sachin seems like a method cook (like they say method actor). In previous challenges when he had to use his imagination and be spontaneous, he failed. I am not saying following recipes is easy, coz it still requires cooking skills and dexterity. Just pointing out his strength.
