What could i use instead of an refrigerator?

If you don’t have a refrigerator, you can use a cooler with ice packs or ice to keep perishable items cold for a limited time. Additionally, you could store food in a cool, dark place, such as a cellar or basement, and use airtight containers to prolong freshness. Fermenting, pickling, or canning are other methods to preserve food without refrigeration. Lastly, consider purchasing non-perishable items like dried goods, canned foods, or vacuum-sealed products.
