Sure. I wrote a Chrome extension that finds recipes on websites you visit and clones them into a big modal at the top of the page so you don't have to hunt them down (they're often buried on long, rambling blog posts). It operates by looking for some divs that common WP plugins and other off-the-shelf recipe site templates use but it has been surprisingly common for me to find itemtype set to "https://schema.org/Recipe" or similar, which makes the process incredibly straightforward.
If more sites adopted the schema properly, it would also be a breeze to convert units on ingredients, extract images and instructions for recipes, and so on. Right now it's on maybe 1/3 of recipe sites I investigate. Ironically, the bigger the company behind the recipe, the less likely they are to use the standard schema.
Some real use cases: bestbuy.com, target.com, apple.com, us.gov, samsung.com, canada.ca, … I could go on. I've read nearly a third of sites use it, especially the larger ones, but also sites that run Wordpress. All with different degrees of depth, but any use can add precision to search and data, that anyone (not just Google, Yahoo, Bing, Yandex) can use.
