It’s not the answer you’re probably looking for but, my cookbooks. I happen to have a bunch of old cookbooks I’ve inherited from family members and friends. It takes some research skills sometimes, but it works.
I also maintain a personal blog site which is my online cookbook. It’s not only my own recipes, but also a link dump. When I find a good, non-AI article I’ll share it there like a clipping with the usual tags for how I catalog things. It takes a bit of discipline, but for me its second nature by now. It also lets me take notes on how a recipe worked out, and what substitutions or adjustments I’d like to make next pass.
