semweb tech is extensible, you could write a specialized schema or ontology to express more detailed information if you want to.
Think search engines for example. This "cooking time" is often displayed as metadata when you search for recipes. You're just annotating a field for the search engine to display in the results.
Schema.org exists for that. Indexing larger granules of metadata. It is built on RDF so if you need something more specialized, you can use the standards to extend it.
This is actually a fun ontology to think about. You'll need to model pans, ovens and all sorts of cooking hardware. I don't see that knowledge often displayed in recipe websites, so microdata probably isn't the best for a specialized system like that. It would probably use the extended schema/ontology just internally, then publish simplified cooking times for indexing.
