@kytta this has been suggested before (but I can't find that toot).

There I also mentioned that a more generic solution might handle that use case.. and a gazillion others: A federated PubSub server app, where publishers send linked data to according to a Profile (in this case a Recipe). They might be vetted on the server by someone, and then they federate to other instances interested in that information. Subscribers, based on specific metadata, receive the content to use for whatever purpose.
