In practice, the process can be a bit tricky. Freeze-dried meals require that you have potable water lying around, which might not be the case in the event of a serious calamity (some Wise Company kits include water purifiers). The cooking instructions for the Wise products I tested call for using the entire four-serving bag at once, which means that you have to have a container on hand to store what you don’t eat, and a fridge to keep it from spoiling. Even at my office kitchen, the only way I could make it work was by pouring about a fourth of the packet in a mug, filling it with water, and putting another mug on top of it.
Know your priorities. There is more to being a prepper than just gathering up non-perishable foodstuffs. There is a lot of thought and process involved when it comes to making sure you and your family is ready in case of an emergency. Here is a list of the things you should prioritize and prepare first, so that you have a good foundation to start with.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
