Well, I know of a fanfiction titled 'Thatch and the Traveling OC'. The OC in this is a traveler who has seen many different cultures and lands. When they meet Thatch, they start sharing their stories, and Thatch is fascinated. He then starts to incorporate some of the OC's ideas into his cooking. This story is great because it not only shows their relationship development but also how the OC can influence Thatch's passion for cooking in a unique way.
