Women don't cook because they don't HAVE TO cook, these days. Unfortunately for some of you, the days of "go get me a sammich, biotch!" days are gone.
Cooking is now more of a hobby for most people. If they enjoy it, they get good at it. If they don't enjoy it, and don't have to cook due to expenses, they can pay someone else to do it for them, whether it is the poor choice of McD's or some healthy restaurant down the street.
Most people learn to cook when they have to cook. Usually due to expenses, many times because they started a family. A girl who can't cook now, will probably be a cook when she has a child or three to feed. Whether she gets any good will probably have to do with if she finds it enjoyable. And it may not even be her. Maybe the husband will be the cook in the family. Cooking is no longer a woman's JOB. It tends to fall to whoever likes it better, and they are usually better at it.
My boyfriend's father is an amazing cook, from what I keep hearing. I just really hope that my BF learns before it is too late, because he appreciates it so much.
The iqqster is a pretty damned good cook. Further fuel to the fire of the secret haterleague. My specialty is spaghetti and sausage (HOOKED UP!!!), and I grill a mean steak. An ex or two have emailed me to whine about how they literally dream about my cooking.
The great thing about people who can't cook is that they can learn. And once they take an interest in it, they could be really good. Cooking is no lost art.
