what this one guy learned from harvest moon:

Seriously. Everyone knows that butter is made by throwing a bottle of milk into a magic machine and waiting a half a second.

Also, grapes, turnips, tomatoes and cabbages require equal amounts of watering and can grow big, tall and healthy right next to each other.

*note: in the PS1 version, cheese is made by throwing a bottle of milk in a magic machine, and I think butter is made by using a whisk and a bottle of milk- it involves a pot too... I need to replay.
