There is nothing wrong in discussing matters related to food. This is mainly because food is the most important driving force behind all our efforts.
Food has different variations. I have seen several houses where new recipes are discussed between the mother in law and the daughter in law in a very cordial atmosphere. I have also seen very young girls learning the art of cooking through you tube, in a very big way, with the husband sharing a good deal of the process of cooking. More so, among the IT professionals.
Food, when prepared and given to others, takes a new turn and there is happiness all around. For example, in the month of May, every year, in every small town and in several villages there is an annual festival called the "Amman Thiruvizha". Though there are quite a few religious activities associated with this one or two day festival, the most interesting part is the huge amount of food prepared by voluntary organizations and given free of cost to anyone who lands there, irrespective of whether he or she attends the festivities or not.
Not only food, water, cool drinks, butter milk and what have you, are also arranged and given to anyone who wants it. The occasion itself brings about communal harmony, and there is no difference between communities or even religion, as there are even Muslims and Christians who not only participate but also donate huge amounts for preparing food.
This is a summer special in most of T Nadu. As regards wastage of food in marriages and other family functions, it is very sad that a huge amount of food gets wasted. In marriages, it is fine if the items are served only after the people sit down to eat. If the items are served even before the guests arrive, the wastage tends to be very huge. I personally think that we should take this rather seriously.
Of course, new recipes need to be tried out even in hotels. When the hotels themselves become famous, the food items and even special food items will become the talk of the town.
