Paprika for iOS took me pretty far in this direction. I bought it on a recommendation from a friend so I could strip out the blog posts and index recipes, but the grocery shopping features ended up making it something I used all the time. You still share with the original URL, but I've got friends who are into cooking on it now and it's just as quick for them to save.
Emailing the recipe formats the content into an email body text and doesn't require the recipient to go to the website. It also includes a .paprikarecipe attachment for direct import into the recipients Paprika app.
