Fluff, marshmallow sprd, 7.5-ounce is still produced by the same batch process developed over 75 years ago - it's the only marshmallow creme made in this manner. It's what makes Durkee-Mower's product so fluffy, white, and smooth; it's what makes the difference. Because Marshmallow Fluff is made only with the finest ingredients under the most demanding sanitary conditions, it requires no artificial preservatives.
