I just posted in your thread re purchasing an oven.
Paired with this thread I have a suggestion for you.
You want to learn to cook.
From what info I was able to gather from your posts you may need to take a few basic classes.
No need to go all out and enroll in a culinary school.
Look around in your area for some classes.
There is an adult learning center that offers beginner cooking classes ( as well as a host of other hobbies)
Don't have the catalog at hand...
