I use nextcloud cookbook but I would really love another or a federated alternative. It does its job but I don't think other people I know would use it.
I've tried several, but I've had a major incident and lost all of the recipes I had because of a database corruption.
So I decided against keeping recipes in databases. I migrated to Notion, but I kept looking for a replacement since that's not self-hosted. Eventually I ran across Silverbullet, and I've been using it for everything, so far it's been great. Not exactly specifically what you asked but it can be used for it and works great.
Hahah, enjoy my upvote for speaking what all of us have thought at one time or another.
I think I've finally hit an ok point with backups: 3 copies of everything at home (on spinning disks), with one backup in the cloud. And I'm working on building a backup system between my brother's house and mine.
