What is Marshmallow?

What is marshmallow?: 
A marshmallow is a CANDY.

How it was made?:

1. Traditional marshmallow: combination of marshmallow root, whipped egg whites, vanilla extract, and sugar. Now days, marshmallow root is more difficult to find, and now replaced by gelatin, usually derived from the bones of animals.
2. The finished product shaped and cut into one inch (2.54 cm) or smaller cylinders and may be rolled in powdered sugar or cornstarch, giving the exterior a dry texture.
3. Because of the marshmallow contains gelatin, it is often not consumed by vegetarians, and may be considered not Halal by Muslim.
4. Marshmallow cream generally does not include gelatin, and can be used in place of marshmallows for recipes like Rice Krispies® treats.
5. Alternately, when one can obtain marshmallow root, carrageenan or agar, one can make homemade marshmallows.
