Another is that many of the things that cost less time, money, and effort to make at home need a recipe that is not easy to find.
I would encourage anyone with a computer to simply do a Google search for recipes, they are everywhere. YouTube has a ton of videos. Just use the search feature. After that, it's just a matter of finding something you can do and/or finding the recipe that you like the best.
It helps to know it can be done and see how other people did things.
Yes, I use YouTube to see how other people did things.
Thankfully, another facet is that it isn't all or nothing. A person can start and gain benefit from even small changes.
Agreed. At 62 years old, I attended a Senior Citizens monthly cooking class that was offered locally for free. The instructors would show us how to cook a new main dish, a side dish, and a dessert at every meeting. I have a binder full of recipes from that class.
The instructor asked me if I was ever using any of the recipes from class at home. I was honest with her and told her that I only used a few of the recipes that were easier to make, but that my main purpose for attending class was to learn how to cook in general and that is why I attended every month. I was applying what I learned at the monthly cooking class to cook the food we normally eat at home.
Unfortunately, the funding for that Senior Citizen's Cooking Class dried up and the classes were canceled. But it was a great experience for me while it lasted.
As the token male in the class, I asked lots of beginner questions when I first started attending the classes. But, in small steps, I learned more and more and over two years really made a lot of improvements.
Our local food bank has some dedicated people that hand out food to those in need. In theory, that's a great service. In practice, I know some people who get food aid, and they have no idea how to cook that food. So, it just gets tossed into the garbage. Maybe a box of macaroni and cheese makes it to the table, or ready to eat soup out of a can is heated up in the microwave, but actually cooking raw veggies or dried goods is beyond them. They don't have the skills to cook that food and nobody is teaching them how to cook.
As bad as it was to force boys into shop class and girls into Home Economics when I grew up in 1960's and 70's, at least our girls knew how to cook and us guys knew how to swing a hammer and change the oil in the car.
