I think especially the videos that show the process, like J. Kenji's, are pretty good (don't expect to be as fast as him when making things, though). But you still have to try it and practice, not just watch.

The part of cooking I'm struggling with right now, and would love some guides and content on, is how to prepare a menu and plan groceries. It's a lot of work, but I'm sure there are ways to make it easier.
