Preparing the Food

Before you start cooking, it’s important to prepare the food. This includes soaking freeze-dried foods in water and rehydrating them. It also includes opening canned foods and draining any excess liquid.

Soaking Freeze-Dried Foods

Freeze-dried foods need to be soaked in water before they can be eaten. The amount of water you need to add will vary depending on the food. Be sure to read the instructions on the package carefully.

To soak freeze-dried foods, place them in a bowl or pot and add water. Stir the food until it is completely submerged. Let the food soak for the amount of time specified on the package. Once the food has rehydrated, it is ready to eat.

Rehydrating Freeze-Dried Foods

After freeze-dried foods have been soaked, they need to be rehydrated. This can be done by boiling the food in water or by microwaving it. To boil freeze-dried foods, bring a pot of water to a boil and add the food. Boil the food for the amount of time specified on the package. Once the food has rehydrated, it is ready to eat.

To microwave freeze-dried foods, place the food in a microwave-safe bowl and add water. Microwave the food on high for 1-2 minutes, or until it is rehydrated. Once the food has rehydrated, it is ready to eat.

Opening Canned Foods

Canned foods are easy to prepare. Simply open the can and drain any excess liquid. The food is then ready to eat.

Draining Excess Liquid

When you open a can of food, there may be some excess liquid. This liquid can be drained by pouring the food into a colander or strainer. Once the liquid has drained, the food is ready to eat.
