This is also common in other languages. Indonesians use enak (tasty) for almost any positive quality. Even in English people refer to attractive members of the opposite sex as "tasty"

But "heer" in Dutch is either a (human) lord or God, so "heerlijk" means lordly or godly, and over time this became more general.

Much the same word exists in German, "herrlich", but it means "beautiful" or "splendid". Same idea though.
