You can set any saved collection to “Fixed” on the WP Recipe Maker > Manage > Features > Saved Collections page:

If you’re not seeing the “Fixed” column, make sure to enable it through “Change Columns” in the top left of the screen.
Anyone visiting the recipe collections feature on our demo site will have that fixed collection showing up. As the admin I could then change this set of recipes next month, and present my users with a different set of recipes that they can use, for example.
