(I Am Solo) The secret behind Young-ho's duck stew from Season 33 (feat. Something suspicious)

‌

That is the duck stew Young-ho supposedly brought home (there wasn't even any separate broth in the bag he carried; it was just that and some side dishes like those below).
Doesn't even a typical Samgyetang (ginseng chicken soup) look bigger than that when it's takeout? lol
When he put it in a pot to boil the next day, it looked somewhat convincing, whether he added water or broth,
but while watching the original broadcast, I was wondering why he was acting so restless over what looked like leftovers he brought home. haha
I doubt he actually brought home leftovers, but would even a single duck leg fit in there??
I'm really curious what kind of takeout duck stew that is...
