Seven minute frosting is a catch-all name for any homemade icing that takes a short time to compose. The ingredients generally include combinations of sugar, vanilla extract, corn syrup, egg whites or cream of tartar and used to create a sweet topping for cookies and cakes. Seven minute frosting is used straight away or it can be stored, both in the refrigerator and freezer, to be used at a later date.
Spoon the mixture into a clean, plastic air-tight container. Do not use a glass bowl that is then covered with plastic wrap as the frosting might pick-up the odors of surrounding food.
Secure the lid on the plastic container and store the seven minute frosting in the refrigerator. Set the bowl onto a shelf that is kept away from any strong smelling foods, such as fish or dishes that contain garlic, for up to two weeks.
Remove the bowl from the refrigerator and allow it to reach room temperature, which is around 72 degrees Fahrenheit, before using. Stir the frosting once it has reached room temperature in order to remove any air bubbles and improve the frosting's overall texture.
Spoon the mixture into a clean, plastic air-tight container. Avoid using plastic freezer bags as these will not as effectively prevent any odors from seeping into the frosting.
Secure the lid onto the container and store in the freezer for up to four months.
Remove the plastic container from the freezer and allow the seven minute frosting to thaw completely in the refrigerator before using. Once again, bring the frosting to room temperature and stir before using.
