The only remaining recipe program for Linux - Gourmet - has been removed from more and more distros because it's python 2 based (among other things), yet there's no current work in progress to port Gourmet to Python 3.
Since I've got more than 200 recipes collected in Gourmet I was quite concerned about my collection, so I decided to do something about: create my own recipe program, Qisit. It's still in the early stages of development, yet it's quite usable - I myself use it productively (with caution, of course, like backing up it's database). It's able to import Gourmet's db so you can continue using your recipes. It's written in Python, using PyQt5 (among other things) mnowiasz/qisit
