I'm looking for a manga about a girl getting reincarnated into the body of a concubine (queen), where she is asked to apologize to another concubine - who accuses her of something - infront of the emperor but instead refuses and slaps the other party.
- she gets sent to the cold palace.
- she is offered poor meals so she goes to the kitchen directly and ends up fighting the cheif and queen prior.
- she eats noodles that give her chi (power) then is visited by a spirit of sorts that gives her a pot and spatula (that can turn into any cooking utensil).
- she uses said spatula for fend off assassins.
- she later meets a child and feeds him some egg rice (?).
- she latter finds out he is her son.
- the kid suffers an allergic reaction from the eggs and she helps heal him with one of the 2 drops of healing potion she has, after arguing with the emperor.[m]

The name of the manga is holy chef, crazy empress
