Could you please help me find some folklore?

The Brothers Grimm recorded the story "Der süße Brei" about a magic porridge pot.
When instructed, it produces food until told to stop. One day, the owner forgets the magic word and the village is engulfed in porridge.

If you are NOT German or English, does your culture have a similar cautionary tale?
If so, what foodstuff is it about?

Thanks gang, boosts appreciated.
