the dying art of cooking

Being a late entrant to the world of cooking, I sometimes feel this is one of the most underrated arts which is dying fast. More so for a country like India where it is said that
the cuisine changes every 100 metres. Though we Bengalis or Tamilians or Malayalis are very protective as well as possessive about our culture and language, we don't really work towards protecting our food.
It makes me wonder whether we will soon lose all the spices and secret recipes which our grandmothers got handed down from generations altogether. Though mixed marriages have also contributed to the taming down of ethnic food as we call it, I think it is also the hectic lifestyles and demanding jobs which have made most people depend on cooks. So you can get a perfectly bengali meal in a Kashmiri household or see a Punjabi family have dosa and idli for breakfast.
But as a very proud member of my Bengali community I feel we all should work towards preserving our food also akin to the way we protect our culture and language.
Just imagine should we not learn to make 'chingrir malaikari', 'patol pathuri', 'doi-koi' and 'bhapa-ilish' for our children. Or do you want them to eat mcdonals burgers and pizzas.
So my suggestion to the new-generation parents, learn cooking!
