In the 09/03/2021 John Mueller hangout, one webmaster was concerned regarding structured markup for recipes.
There are a number of sites using structured markup for lists of recipes showing up in the top stories carousels.
John explained he thinks it’s a bug. He thinks this is something that Google shouldn’t be showing rich results for. In their guidelines for structured markup for recipes, the only thing that should be marked up is one item on the page.
A list should not be marked up with structured recipe markup.
John thinks the smarter approach would be to see if they can algorithmically deal with the websites that are using structured recipe markup on lists rather than individual recipes.
He mentioned that the better solution would be to see if there’s a way to scale this instead of manually chasing everybody down.
