Use hRecipe for creating Google Rich Snippets, for leveraging SEO results, and for attractively displaying your recipes.
Unzip the plugin into your wp-content/plugins/ directory. It should automatically create an hrecipe/ subdirectory.
In your WordPress admin page, go to the Plugins section and Activate the "hRecipe" plugin.
When you go to "Write Post" or "Write Page", click on the knife and fork icon to pop-up a simple form. (Or hRecipe button for text formatting)
Fill in the fields of the form.
Click Insert and the contents of the fields will be inserted into the page or post you were composing, but marked up using the hRecipe microformat.
