A marshmallow is a sweet made from sugar, gelatine and egg white.
The name is taken from a plant, the marsh mallow, a relative of the hollyhock, which grows in marshy places. A gum extracted from its roots was formerly used to make jellied sweets .
Marshmallows are made commercially in small squares or circles and coated in fine sugar, desiccated coconut and sometimes chocolate. They are sometimes toasted and often used as decoration for desserts and cakes or melted to make a sauce.
