For one to get married to a lady who can't cook, the other party should have noticed this during the period of courtship. And if the decision is to get married, then ways to overcome this challenge would have been discussed before marriage. Some of the ways include:
* Learning to cook which should involve both parties so that it would be fun and not look like forcing one to go through a task.
If I didn't know about it before marriage, then it becomes my responsibility to either teach her or pay someone to teach her or better still send her to a catering school where she would learn more than I know
As it is said, Love covers all things, therefore knowing fully well that your wife is a bad cook before you married her, means that you have alternative plans in mind. The best you can do is to encourage your wife to learn. treat her with love while raising her up to your standard in terms of your delicacy preferences.
