obviously they are talented and that's why they are here...the point is do they have knowledge about different cuisine or are only experts in Indian cooking...This is not a learning show...yes people learn during such shows but some basic knowledge is required...I doubt if khoku or yasmeen have basic knowledge about baking as well...it's easy to make something if the recipe is in front of u...but there are things which come only with experience...like in baking...how much the batter should be mixed, what should be it's consistency etc etc is different for say cakes and muffins...this will only come with experience...just like Indian cooking...the winner should imo know at least the basics of other cuisines/baking as well and not only Indian cooking!
I can't say if they all are very talented and that's the reason they are there- but yes they have their plus and minus points. I am sure the producers won't be able to get 12 (?) contestants good in all aspects of world cuisine or even indian cuisine as even indian cooking varies from one state to another.
I did not say it's a learning show. It is a competition and Khoku has proved time and again (pizaa, strudel) that she doesn't need to know it beforehand but she would still cook something as good as or even better than the others do. According to me cooking is an art and you are either good at it or not and she is a born cook. That doesn't mean I think she's going win as the odds are stacked against her.
