"Secret Combination" was composed by Konstantinos Pantzis with lyrics by Poseidonas Giannopoulos. Giannopoulos had previously written the lyrics for "Comme ci, comme ça", which represented Cyprus at the Eurovision Song Contest 2007, while Pantzis had worked with Kalomira on her previous two albums. In an interview with ESCToday, Pantzis described "Secret Combination" as an R&amp;B song with an "American production" style. He added that it also incorporates Greek and Mediterranean sounds, such as the toumperleki. It was recorded at Prisma Studio, mixed at the latter studio and C&amp;C Studio, Athens, and mastered by Leon Zervos at Sterling Sound Studios, New York City.
