How do I get rid of a stew i made??? it does harm to my village and i want it gone. what do i do??

Do one of the following: wait for about 15 minutes, quit the game, or switch to a different player slot.

I was going to say wait for a while ... it will disappear after a while if no one is paying attention to it ... and usually you have to drag them over to the stew to MAKE them eat it ... the exception being the exercise stew ... some of them have learned to eat that on their own!!!
