[Plugin: ReciPress] Required fields missing

When I run a page that’s ReciPress enabled (http://norecipes.com/blog/2012/01/15/nikuman-baozi-recipe/) through Google’s Rich Snippets Test Tool (http://www.google.com/webmasters/tools/richsnippets) I get two errors:

Warning: Missing required field “updated”.
Warning: Missing required hCard “author”.

I thought maybe there was a problem on my end so I ran a post off your Showcase site “(http://www.10-minutemeals.com/recipes/talapia-and-pico-de-gallo/) through the tool and it too is showing the same errors.
