4Scoop into a storage container such as a glass jar or resealable gallow plastic bag. Store in the freezer, where it will remain soft and scoopable indefinitely. Don't try to keep it for more than 1 or 2 days at room temperature as it will then weep and disintegrate.
5Great to top ice cream or put with peanut butter in a sandwich. Use as you would store Kraft Jet-Puffed Marshmallow Creme. Makes 2 1/2 cups.
