Some time ago, we introduced the `cookAsync` instead of the existing
`cook` function, and planned to migrate everything to it. Then after
migrating, we wanted to raname the function to simply `cook`.
I've checked Core and plugins, and currently we call `cookAsync` everywhere,
there are no calls to the `cook` function anymore. So we're good
to proceed with this refactoring.
This PR makes the first step by making current cookAsync and cook functions
do the same thing. Effectively now the `cook` function becomes an alias
for the `cookAsync` function.
