Just saw this thread. Think it's a good idea.
Myself, I really enjoy cooking. Used to spend more time doing it before I had kids and the more constrained meal times. Still cook 90% of our family's meals, including a full roast every Sunday.
The trouble I've been having is that whilst I used to cook something new almost every night, and learn something in the process, over the past decade I've been gradually descending to where I am now, which is going through the same limited repertoire (roast dinner, chicken puttanesca, hunters' chicken, carbanora, salmon tagliatelle, Thai or Malaysian curry, fish pie, mirin salmon, and not much more, tbh).
I actually feel I'm losing my improvisational skills. My wife is still impressed that I can whip up a meal from ingredients when we've not got much in and when she can't see a potential meal from whatever's leftover, but it's a bit limited. Like, quick batter for pancakes, fritters or tempura, something based on a basic white sauce, white wine sauce or tomato sauce, mustard sauce... you get the picture.
So, I'd really like some recommendations for books, Youtube videos, etc. that would give me the basic skills I lack and up my improvisational game. I picked up The Essentials of Classic Italian Cooking, which I'm slowly working my way through, but would be good to pick up some skills to cook other styles too.
