Other forms: marshmallows
A marshmallow is a soft white sweet that toasts over a fire. Toast marshmallows, a bag of marshmallows, marshmallows in cocoa.
It was originally made from the root of the marsh mallow plant, which grows in salt marshes and gives a soothing sap — that plant is where the name comes from and no modern sweet contains it. The marshmallow test is a famous study of children and self-control.
