A marshmallow is a sugar candy that, in its modern form, typically consists of sugar, whipped to a spongy consistency, molded into small cylindrical pieces, and coated with corn starch. Some marshmallow recipes call for eggs.
A popular camping or backyard tradition in North America, the United Kingdom, New Zealand and Australia is the roasting or toasting of marshmallows over a campfire or other open flame. A marshmallow is placed on the end of a stick or skewer and held carefully over the fire. This creates a caramelized outer skin with a liquid, molten layer underneath. According to individual preference, the marshmallows are heated to various degrees — from gently toasted to a charred outer layer. Often, the latter is achieved by igniting the marshmallow. The toasted marshmallow can either be eaten whole or the outer layer can be removed and consumed separately and the rest of the marshmallow toasted again.
