Recipe sites are notorious for SEO tactics. They all follow the same highly optimized format with the stupid story about the author's grandma and how they just couldn't get enough of these cookies, and how the recipe was lost for 90 years until recently their great great uncle Lou found a copy of the recipe in an old donut.
Google has all of the tools to solve recipes. Make Google Recipe with a standard template and a way to link in and out of YouTube. People who contribute popular recipes get ad revenue. People with recipes and YT videos get even more. Adding ways to find similar recipes would be a killer feature. Who hasn't found a recipe that was almost what they were looking for, but was missing that je ne sais quoi.
