I guess the use case you mentioned is more to adding variations like an alternate ingredient, or a tip to a step or something like alternative to what is suggested in the original recipe.

We have a wish list in our mind where we can add structured annotations (tips/alt ingredient/photo) to the original literature and have a repository of such stuff residing on top of the original recipe itself.

This way it can become a far more richer data, set in the original context and offer mutual learning to all.

Thoughts?
