Support `cookingMethod` for recipes

[jessebot]

Is your feature request related to a problem? Please describe. Not really, just looking for a way to easily spot the cooking method when looking through recipes.

Describe the solution you'd like It looks like cookingMethod is a thing for the schema.org/Recipe schema: https://schema.org/cookingMethod

I'd like to be able to have a method like deep fry or oven baked, or even combinations for like some cheesecakes, which are two things: oven baked,refrigerated

Describe alternatives you've considered I guess users can just use the tools field right now, or do a fuzzy search, or use keywords, but keywords are just really getting out of hand for me personally.

Regardless, this isn't a hugely pressing feature request, just a nice to have.

Thanks for all you in the community and maintainer squad do :)
