This is a rough draft of what I have so far. Just make an event and go to the third page of the list of event commands and click Script. Type in this code:

CODE

$scene = Scene_Cooking.new

To change what variable the item is stored in, go to line 81 of the script.

Hope I was at least kind of close lol:
