Asif mate...men clearly can cook if they put their mind to it...the reason desi boys dont cook is becuase they dont bother not becuase they are incapable...
But as for chefs...i agree with ManwithaPlan that as a career men deal a lot better with the pressures...men will listen to a man in the kitchen not a woman...men can command respect in the kitchen and will handle the stress that much better...
Also i genuinely believe men to be a lot more innovative...men tend to experiment a lot more with cooking whilst girls stick to what they know and have learnt...generally this comes from the fact that for men its fun and not just something they have to do...
Granted though Asif that more girls cook than men...but the question was about male chefs being better not how many males cook...
I don't see why men cannot cook good food (in fact they do, thus the reason why most famous chefs are men) so that "Men can't cook better than Razia and Safia" is completely false.
