Hi pureherbivore.
Thank you for contacting us and for trying Kale. We appreciate it.
You could try to solve that using categories and then put them up on the Main menu. Please see this – http://www.wpbeginner.com/beginners-guide/how-to-add-topics-in-wordpress-navigation-menus/
Simply create categories “recipe” and “general” (for instance) and add them to the Main menu. Once you click on the general category all posts within that category will be shown and the same applies to the recipe category.
Hope this helps but if you have additional questions, just ask.
Kind regards.
Thanks so much for your help!
