Storage Tips: If you’re planning on storing your ice cream beyond a few days, press a piece of plastic wrap on top of the surface of the ice cream and then secure the lid in place. This will help prevent ice crystals from forming when the ice cream is exposed to air. Store your ice cream container towards the back of the freezer where the temperature remains more consistent and to prevent it from warming every time the freezer door is opened. The continually warming and freezing cycle likewise causes the formation of ice crystals.Homemade ice cream is best eaten within 1-2 weeks, after which the texture will begin to degrade.
