It looks like Bing is testing our introducing a different way of showing rich results on desktop. For recipe related queries, Bing is displaying a carousel that features just three recipes initially. It lets users filter results by total time and other nutrition criteria, but doesn’t immediately show the option to compare recipes.
Some people are still seeing instances of Bing’s recipe treatment of a page-width carousel that gives users that ability to select and compare recipes directly from the results page.
With the new carousel, the comparison option is available after a users selects at least one or more of the filters. The Bing recipe comparison pages features elements such as rating, total time, nutrition and yield, which are all properties from recipe schema.
