Why You Should Start Storing Your Ice Cream Tub In A Plastic Bag

Why this simple trick works

The effectiveness of this hack stems from the nearly airtight seal of the freezer bag and the extra layer of insulation it offers. Cold air is generally drier than warm air, which means that the interior of a freezer is often quite dry. Freezer burn happens when the moisture in your stored food evaporates, leading to the formation of ice crystals (if you're interested, here are some common signs that your food has freezer burn). As mentioned earlier, this can negatively impact the flavor and texture of your food, particularly ice cream, which needs the right moisture level to stay creamy and soft.

The plastic bag helps retain moisture within the ice cream container, where it should be. It also ensures that your ice cream stays at the optimal temperature. With this hack, any temperature changes—whether warm or cold—must pass through both the bag and the cardboard carton. Since freezer bags are less porous than most cardboard, they shield your ice cream from melting and refreezing when the freezer door is opened. This helps to prevent the formation of ice crystals that can make your ice cream hard and unappetizingly crunchy.

Whether you're preparing homemade ice cream for storage or looking to safeguard a newly found alternative to your favorite discontinued Häagen-Dazs flavor, using a plastic freezer bag is the simplest solution. If you want to add an extra layer of protection, consider placing a piece of plastic wrap under the lid to help create a tighter seal. By following these tips, you can greatly extend the shelf life of your ice cream.
