When I was eating keto, I got frustrated with how bad the search functionality was on all the keto blogs, so I made a similar tool It's a keto recipe searcher/aggregator:

https://ketohub.io

During this, I ended up going down a long rabbit hole trying to figure out how to parse recipe ingredients properly, and eventually spun off a separate ingredient parsing service:

https://zestfuldata.com (the service)

https://mtlynch.io/resurrecting-1/ (a 3-part blog series on how I built it)

OP - if you're interested in adding ingredient parsing to the site, I'd be happy to work with you.
