Thank you so much for adding OurGroceries - I was using the HACS version previously GitHub - ljmerza/ha-our-groceries: Our Groceries Integration for Home Assistant (and still am).
The official integration pulls in lists but does not get recipes (which are just another type of list) - this would be an awesome feature to have please!
Thank you.
I think it was mentioned in the release party that more features were added in the back end that needed front end code approval, so expect additions for the next release. (I believe that is what was said. Same question came up in the release, look at the YT video for more details.)
Jump link to the section…
Sadly nothing about recipes in the vid but looking at this part of the code…
It’s possible to get the recipes with:
recipes = (await og.get_my_lists())["recipes"]
The new official integration uses the same Python module as the unofficial HACS version: GitHub - ljmerza/py-our-groceries: Unofficial Python Wrapper for Our Groceries
I’m not a Python guru by any means (I work as a sysadmin and mostly do shell scripting) but have made some very small contributions to the module and wouldn’t mind giving this a stab, if I can get the time. 
A year later and sadly this has still not been addressed.
