I've been looking for a way to index my mother's recipes in a useful way, was somewhat motivated two years ago.

I wanted something that:

1. produced well formatted PDFs for printing (my mother prefers paper).

2. it would substitute different ingredients. i.e. this recipe contains milk, a simple button or keybind would change it to an appropriate milk substitute.

3. automatically produced different measurements.

I tried GNOME Recipes [1] as it checked a lot of boxes but it has some big bugs still that make it basically unusable.

I considered maybe doing something org-mode and emacs, but kind of lost interest after that...
