This tutorial features the Feast Plugin, which contains theme enhancements.
The Edit Post Info feature enables bloggers to customize the post info of their recipe pages. Customizing and improving your post info allows you to gain an advantage over food blogs that haven't put the time and effort into these areas.
It completely overrides whatever is in the theme default + Genesis Simple Edits.
How it works
It's no secret that visitors and search engines love details. Easily edit your post info to provide the date published, date updated and other details such as disclosures.
We've long advocated that your recipes should be evergreen and that dates shouldn't impact your content, and we still do.
But recent data shows that having date published and date modified are a good user experience, and may help search engine ranking due to additional schema.
Note: This only updates the post info on the post page. We do not recommend that you display post-info data on the home page or category pages.
datePublished and dateModified schema
Here's Google's John Mueller re-iterating that showing the published (and last modified) date is good for users:
Link to your author profile to increase your E-A-T and improve search engine rankings.
Your post_author_link is set in your Admin -> Users -> Your Profile -> Website field.
The Feast Plugin's disclosure shortcodes have been deprecated, but you can create your own following this disclosure shortcodes tutorial.
Disclosures shortcodes don't need to be put into the Edit Post Info, if they don't apply.
But they can also be put into the post content on a post-by-post basis.
Conditionally display modified date
This code snippet from Bill Erickson on conditionally displaying the modified date is an option, but we don't offer support for it.
It's a nice tweak if you can hire a developer to do it for you, but will have basically zero impact on SEO or how users perceive your post.
