Marshmallow

My was talking to my dad about the marshmallow with chocolate coating sold by my school's consumer's club(Kelab Pengguna in bm.) while we were having our dinner. Then, suprisingly he ask:'Marshmallow is a fruit right?' I was like: O.O ... Then i told him that marshmallow is like cookie, a process food. Then he disagreed, and said:'no lah... marshmallow is fruit lah...come from tree want...' Then we fight fight fight... just for truth of "Where does marshmallow come from".
