Okay, so I'm trying to display my static method to the screen. I know I'm not using the console like Alena in Workspaces but I really don't see why the method isn't working.
What I'm actually getting is all the echos from the cookbook.php file but Alena left those in and we only see the output from the method.
http://www.jonniegrieve.co.uk/jg-lab.co.uk/php-cookbook/cookbook.php
Note: I'm aware I'm pulling in the same HTML twice with the include
I've included the Render and the Recipe class.
I've put the displayRecipe() method in the Recipe class.
Here's my php files as i have them at the moment,

Treehouse Moderator 91,252 PointsWell it looks like I've worked it out.
I'm fairly certain having slept on it I was still only getting the echoes that were appearing on the cookbook.php file and the displayRecipe() method wasn't displaying. I may have been wrong but it doesn't matter now. :) After a bit more tinkering I was able to format the method and displaying it, switching new line escape characters for the
<br />tag since I'm outputting to HTML.
