Google Removed Guidance About Specifying A Range For The cookTime and prepTime In The Recipe Documentation
https://developers.google.comGoogle has updated the guidance about specifying a range for the cookTime and prepTime properties in the Recipe documentation.
Currently, the only supported method is an exact time; time ranges aren’t supported.
If you’re currently specifying a time range and you’d like Google to better understand your time values for cook time and prep time, we recommend updating that value in your structured data to a single value (for example, "cookTime": "PT30M").
