Why are marshmallows and cocoa so good together?

Is it something in the added creaminess without the addition of cream? A textural element? Nostalgia?

The cocoa was a gift, given generously by someone in my chosen (rather than birth) family. It's not handmade, the marshmallows came from who knows where, but it is all worth savoring anyway. In fact, it's delicious.

Happy Holidays.
