Once created from the sweetened extract of the roots of the marshmallow plant, this sweet is now commercially made from corn syrup, gelatin, gum arabic and flavorings. Light, fluffy marshmallows come packaged in regular size (about 1 1/2 inches in diameter) and miniature (1/2 inch in diameter). They may be white or pastel colors. Marshmallows are used variously to top hot chocolate and dishes such as sweet potatoes. Marshmallow creme is a thick, whipped mixture available in jars. It’s used in fudge, as an ice-cream topping and as a filling for cakes and candies.
