That's not enough. I have several good cookbooks (and some OK ones, and one that instructs me to have my fishmonger clean the squid). I still miss the collection I left behind when I moved out of the states.

But they don't fill the same niche. Cookbooks tend to do an excellent job teaching or introducing me to things I might not have otherwise cooked or searched for. The internet helps me when I have a specific ingredient I need to use up, if I am lowish on ingredients, or need something special that the cookbooks that I own simply don't offer. And sure, I could use cookbooks in a similar manner, but it isn't efficient and I don't always want to spend that sort of time.

I have a table in Notion where I try to put in every recipe I followed and liked the result, and it also has a column for required ingredients. That solves the specific ingredients problem, but it is a lot of effort.
