How can I preserve food without a refrigerator and freezer? Is there a way dry ice can help with that? Like are there other methods for preserving food that would normally be stored in a freezer. Thanks everyone.

When using salt for preservation get the pickling salt, it has the correct acidity and won't turn your food weird colors. It also keeps vegetables crisp longer.

Pickling salt is simply sodium chloride, there is no acid added. Table salt on the other hand has anti caking or flow agents added as well as iodine, and it's the iodine that discolors vegetables.
