Googles Semantic Based Recipe Search

More semantic goodness being used:

the entire search is built on structured data that webmasters have built into their webpages using markup code that’s invisible to humans but is extremely useful to machines. The dream of the so-called semantic web is built upon the idea that web pages will be full of such underlying tags so that search engines can parse a webpage to learn someone’s e-mail address or know exactly what a restaurant’s operating hours are by scanning underlying code invisible in the browser.
