Does anyone know what I do with Cocoa beans?

It dropped after following a ghost in the small graveyard. Does anyone know what to with it, cant find anything on the wiki.

Im assuming itll be a later update where we can grow cacao trees, ferment and process the beans into chocolate. Maybe even make cacao butter...? Hopefully?

How did you unlock the graveyard?
And possibly try planting it?
