Marshmallows are a soft, spongy confection made primarily from sugar, water, and gelatin, whipped to a light consistency and often coated in cornstarch or powdered sugar. Originating from ancient Egypt, the modern version was developed in the 19th century and is now a beloved treat worldwide, especially in desserts like s'mores and hot cocoa.
Marshmallows are almost entirely carbohydrates, specifically simple sugars, with virtually no fat or protein. A single large marshmallow provides about 25 calories, offering minimal nutritional value beyond a quick energy boost.
