When recipe information is marked up in web pages, Google may use that information to display filters for recipe results and for inclusion in Google with Recipe View. The goal of a recipe rich snippet is to provide users with additional information about a specific cooking recipe, such as ingredients and cook/prep time. This tool makes it simple to add snippets to your own recipes.
When using recipe markup, the main topic of the page needs to be about a specific recipe. Using recipe markup on a page containing multiple recipes is not supported.
