Doing poop-poop is obvious forbidden. Seal their shitting holes before feeding.Next, feed them according to your favour -- actually, it's to prepare fillings in situ*.
Mom often makes manjuus with meat filling, by feeding them high-grade salty preserved meat. Feed them according to your appetite.
in situ: Latin phrase, 'phenomenon exactly in place where it occurs'.
Of course the text didn't use Latin, but I think this word is appropiate (from my science knowledge). Feeding in this way, the manjuus can double their size in a day. Together with the pain, the manjuus should taste great.Other than the manjuus, we also need cooking oil, eggs, salt, chinese celery and green chives. Alright, let's start cooking!
