To learn more, read our documentation on how to mark up recipe information or our general help articles on rich snippets for a more complete overview.Please remember that to ensure a great user experience we're taking a gradual approach to surface rich snippets. This means that we can't guarantee that marking up your site will result in a rich snippet when your page shows up on our search results. However, we encourage you to get started, and once you're done you can test your pages with our rich snippets testing tool.
