I found tandoor, mealie, etc too bloated and complex for a simple catalogue of recipes. my solutions was mkdocs.
i do have to write out each recipe in markdown but this gives me a chance to read each recipe in detail and understand it before it goes into my catalogue.
So far I just keep recipes in whatever I’m using for notes.
Some of these dedicated programs look interesting though. Thinking about it, it would be handy to have some dedicated cooking features, like being able to search for recipes by ingredients.
