Content creator Cosma set out to test every possible sandwich recipe to find the best one.

“A recipe can take me an hour or a day, but I always try to vary between divisive sandwiches and classics.” (cosma_sur_insta)

What a wonderful quest indeed. While having a drink with friends, a coffee break at the office, or a family lunch, who hasn't asked themselves the question: what is the best sandwich in the world? At first glance, it's hard to find the answer, specific to everyone's tastes: subjectivity always ends up adding its two cents. However, Cosma, 26, tries as best he can to decide among the range of infinite combinations. On Insta and TikTok , Louis Cosmao, his real name, is starting his 194th composition in his quest to find the "one sandwich."

A fan of manga and anime, the name of his concept "came out of the blue" as he says, in reference to the famous One Piece by Eiichiro Oda . After graduating from business school, Louis Cosmao launched into digital marketing. He worked for three years for the digital giant Webedia and finally resigned: "I was fed up, I wanted to start my own business."
