Omake Gif Anime - Emiya-san Chi no Kyou no Gohan - Episode 9 - Medea Calculates Cooking

Medea literally figured that Shirou would be the best person to teach her how to boil taro root.

Saber was overprotective as always when finding a former enemy in the house, but she was won over by the taste of taro simmered in broth and Medea's devotion to her own Master.

Medea suffered some information overload when dealing with the other dishes, but she helped Shirou put together a meal Saber couldn't resist eating all at once.
