Hi there,
The game allows the following combination of commands for this action:
- add herb _ honey
- mix herb _ honey
- put herb _ honey
- put honey _ herb
where the _ can be replaced with: in, with, on, at, into, to, for
These preposition are "synonymous" in this game, and can be used interchangeably.
I will try to add the and to the code when I can get access to it again this weekend. (Adventuron is throwing errors right now...)
Thank you for the report!
