I don't understand people who don't know how to cook. Can you read? Have you ever watched a cooking show? Do you have the internet?
It really isn't hard. To cook good it isn't hard either. Butter, garlic, salt, sugar, onion, cheese. If it doesn't taste good yet, you probably didn't add enough of one of the above. There is your first lesson. We'll get into the second lesson (which involves healthier ways to cook since 3 out of my 5 options are not at all healthy) later.
I'll answer this one. I can't cook. Actually, I can, but barely. It involved buying a meat thermometer and a chart telling you at what temperature meat is done at. I can't tell by looking at it unless I wait until it's well overcooked. Same thing happens with cookies...I always wait until I see a little brown at the edges and very top of the center, and by then it's too late. But I can't judge it sooner than that. Also, I always have to look up what temperature to cook different kinds of meat at. Having never closely watched anyone boil, fry, brown, or anything to vegetables, it takes a decent amount of googling to learn how to even cook up just a medley of veggies on the stove. Which ones need to cook longer? Which just a little bit? How can I tell when they're done? When the directions say "until brown/translucent/thick/thin/a sizzle/moderate boil/beginning to blank" I struggle. I google what it's supposed to look like, which of course leads to picture-perfect and usually not that helpful pictures. I read instructions in cookbooks, and at least 80% of the time there's at least one line of instructions that I wish had better clarification. Slow cooker recipes help because I just have to throw in ingredients and let the magic happen, and it's very difficult to overcook the food. A new dish I learned this year was Chicken Noodle Soup. I didn't know chicken boiled through so quickly before this. I always assumed it took hours. Now I know it takes 30 minutes. But the directions have to be "throw in the noodles. 3 minutes later add the chicken and cook for 5 minutes" not "noodles, and when appropriate/time left/at the end/a bit later add the chicken". That throws me for a tail spin.
Also, I have to learn how to chop every interesting kind of vegetable and fruit. Bell peppers took me years to memorize the best way to cut them, and I use them weekly.
I don't have a natural knack for it, I never want to watch a cooking show*, and I'll never enjoy it. I equate cooking to doing laundry or dusting. Not that terribly hard, but certainly a chore. Not something I consider spending an afternoon on, unless it's a serious spring cleaning day or something. I can make basic meals and I have exactly 3 "harder" recipes I know, plus 2 desserts I can make from scratch. So I can cook, but it's at the most basic level. Meat and vegetable, or pasta, or a sandwich.
*Fortunately, my DH loves cooking shows. It's just unfortunate he's not around to cook all that much. But I have learned some helpful things from them. The issue is that it takes 30-60 minutes of TV for me to learn the 2 minute lesson that I'll hang on to.
