Make it works with custom post

Hello,

I love this plugin but I have on small issue with it : I can’t find out how to make it works with my custom “recipe” posts :
Here is one of my page :
http://paleo-optimal.com/recette/cervelle-de-veau-chou-vert-gras/
With common posts it works very well:

Thanks in advance,

Cédric
