I created this by using the mixedit as a template. If you want to have cooking be something more than just a removal of a 'raw' flag on food and want different ingredients and recipes this version is what you're looking for. Make sure to comment out the 'stock' cook command.

For this code to work its best you should:
add a cooking skill (I can't remember if the stock code comes with one)
item container types: pot and pan
add 'cook' as a mix type

Feel free to use this snippet as you see fit, but please keep the tag at the top to give me credit for the time spent on it, especially if you plant to post the code to a web site or ftp site. The DOT license forbids profit made from this code.
