Drying, Dehydrating, and Rehydrating Food: Tips and Tricks

Drying, Dehydrating, and Rehydrating Considerations


When it comes to survival and preparedness, one skill that often gets overlooked is the ability to properly dry, dehydrate, and rehydrate food. This skill is essential for long-term food storage, as well as for creating lightweight and portable meals for camping or hiking trips. In this article, we will explore the different methods of drying and dehydrating food, as well as some considerations for rehydrating it effectively.

Drying Food

Drying food is one of the oldest methods of food preservation, and it is still widely used today. There are several methods of drying food, each with its own advantages and disadvantages. Here are a few common methods:

Sun Drying

Sun drying is the most basic method of drying food. It involves placing the food on racks or trays and exposing it to direct sunlight. This method works best in hot, dry climates where temperatures consistently reach 85 degrees Fahrenheit or higher. Sun drying can take anywhere from one to three days, depending on the type of food and the weather conditions.


Dehydration is a more modern method of drying food that uses heat and airflow to remove moisture. There are two main types of dehydration methods: air drying and oven drying.

– Air drying involves placing the food on racks and allowing air to circulate around it. This method is slower than oven drying but requires less energy.

– Oven drying involves placing the food in an oven set at a low temperature (around 140 degrees Fahrenheit) and leaving the door slightly ajar to allow moisture to escape. This method is faster than air drying but uses more energy.

Electric Dehydrators

Electric dehydrators are a convenient and efficient way to dry food. These machines use a heating element and a fan to circulate hot air, removing moisture from the food. Electric dehydrators come in various sizes and configurations, from countertop models to large-scale commercial units. They offer precise temperature control and adjustable airflow, making them ideal for drying different types of food.

Rehydrating Food

Once food has been dried or dehydrated, it can be rehydrated to restore its texture and flavor. Here are some considerations for effectively rehydrating food:

Using Water

The most common method of rehydrating dried food is by soaking it in water. The amount of water needed will depend on the type of food and the desired consistency. In general, a good rule of thumb is to use about twice as much water as the volume of the dried food. For example, if you have one cup of dried beans, you would soak them in two cups of water.

Using Broth or Stock

Another option for rehydrating food is to use broth or stock instead of water. This can add flavor to the rehydrated food and create a more hearty and satisfying meal. Simply replace some or all of the water with broth or stock when rehydrating the food.

Using Sauces or Marinades

If you want to add even more flavor to rehydrated food, consider using sauces or marinades. This can be particularly useful for rehydrating meat or vegetables. Simply mix the dried food with your desired sauce or marinade and allow it to soak for a few minutes before rehydrating. This will infuse the food with additional flavors.

Tips and Tricks

Here are some additional tips and tricks for drying, dehydrating, and rehydrating food:

– When drying food, make sure to cut it into small, uniform pieces. This will help to ensure even drying and reduce the drying time.

– To enhance the flavor of dried food, consider adding spices or herbs before drying. This will allow the flavors to intensify during the drying process.

– Store dried food in airtight containers or vacuum-sealed bags to prevent moisture from re-entering and spoiling the food.

– When rehydrating food, start with less liquid than you think you need and add more as necessary. It’s easier to add more liquid than to remove excess.

– Experiment with different combinations of spices, herbs, and sauces to create unique and flavorful rehydrated meals.

My 2 Cents

Drying, dehydrating, and rehydrating food are skills that every prepper should have in their arsenal. These methods allow for long-term food storage, as well as lightweight and portable meal options for outdoor adventures. Remember to invest in a quality dehydrator if you plan on drying food regularly, and don’t be afraid to get creative with your rehydration methods. With a little practice and experimentation, you can become a master at drying, dehydrating, and rehydrating food in no time. Happy prepping!
