Sinseollo was originated from the story that a politician
Chung Hee-ryang had become a victim in a massacre of scholars
under the rule of King Yeonsan in Joseon (Chosun) dynasty.
He fled to a remote mountain and was leading a solitary
life like a hermit. He made a pot and cooked vegetable
by boiling in it, to be taken as daily meal. After
his death, his utensil had come to be called as sinseollo,
meaning a fire pot (ro) used by a hermit (sinseon).
And later, the food has begun to be called as sinseonro
or sinseollo.
