I will tell you from experience that one cannot learn "cooking" in a single hour, any more than one can learn "music" in an hour.
I am doubtful it is possible to have the same experience with music, although maybe one can learn things like "what is a canon".
A person in such a situation is going to get very impatient trying to watch most cooking videos which tend to waste a lot of time talking about things unrelated to the recipe at hand.
1) Shopping. What's a good price on X? Meal planning's a factor and takes time, and you've gotta already have some notion of what's cheap right now for that, or else much better cooking skills to be able to make something with whatever you happen to pick up, in which case you also need to be a good judge of how much of each thing to pick up to cover meals for a given period of time. All this also takes time.
2) The actual cooking. Obviously. Takes time, takes skill, takes schedule stability if you don't want to end up with a bunch of "well shit, I guess we're ordering delivery pizza again" days.
3) Cleaning. Even if you're great about clean-as-you-go while also trying to watch kids or whatever, is your spouse? Uh huh. And cleaning as you go is another skill in the cooking department, gotta know when you're done with things, when you have minute to wash a pot without ruining anything, how to prep your ingredients and space and in what order for maximum effect (being other-than-awesome at this adds quite a bit of time to your cooking process). How to clean various things requires a little knowledge and experience, too.
(Of course it can be super cheap and incredibly easy and low-time-commitment if you can convince your family to be OK with rice-cooker rice, beans, and steamed whatever-frozen-veggie-was-on-sale for every dinner. Good luck.)
I'm definitely like that with cooking. It's a hobby of mine but there are nights when I just need something to eat and get on with other things.
Yes, I recently took a knife skills class with a some friends. Technically ran a couple hours and $60, but well worth the expense.
You could presumably figure out the same stuff by watching online videos, but the social experience and getting immediate feedback on physical skills was nice.
Now when you know how to cook one thing you can try out some other stuff which will be small investment because you have some base from cooking that one meal for some time.
I am by no means a chef (so not going to impress anyone with my cooking skills because it still is just basic stuff) but I am not afraid of cooking, I can now quite confidently experiment and I started with baking chicken breasts and boiling rice.
Some reviews of this book point to the recipes being dull compared to some newer books, which while true, misses the point entirely. This is a book that introduces the fundamental concepts of cooking with simple recipes that can be made in 10 minutes. It may be the single best cookery book ever written. It won't teach you a bunch of recipes so much as it will teach you how to think about cooking.
It's also very short, so you could probably read the whole thing in an hour (and if you pause near the start to boil some water, you might even cook something too).
One time I bought a 50 pound bag of onions and practiced cutting/dicing/etc for an hour plus. These days, I cut up an onion (or multiple onions) very nearly on a daily basis in my cooking at home.
