As preppers, we understand the importance of having a long-lasting food supply during emergencies. One versatile and nutrient-rich food item to consider is sweetcorn. Whether you grow your own or find them in abundance during the peak season, dehydrating sweetcorn is an excellent method to preserve its flavor, nutrients, and texture for extended storage. In this post, I will guide you through the simple process of dehydrating sweetcorn, offering you a valuable addition to your prepper pantry for a rainy day.
Step 1: Selecting and Preparing Sweetcorn
To ensure the best results, choose fresh and ripe ears of sweetcorn. Look for ears with plump kernels and bright green husks. Remove the husks and silk, and rinse the corn cobs under cool running water to remove any remaining debris.
Step 2: Blanching for Preservation
Blanching is a crucial step that helps to retain the color, texture, and flavor of the sweetcorn while also ensuring better food safety. Fill a large pot with water and bring it to a rolling boil. Carefully place the corn cobs into the boiling water and let them blanch for 4-5 minutes. Blanching helps to deactivate enzymes that can cause the corn to deteriorate over time.
Step 3: Cooling and Draining
Once the blanching is complete, remove the corn cobs from the boiling water and transfer them to a bowl of very cold water. It is often suggested to add ice to the water, but not everyone wants to spend money on ice or has large bags of ice readily available in their freezer. The purpose of this cooling process is to halt the cooking and preserve the corn's texture. Allow the corn cobs to cool in the cold water for a few minutes, and then drain them thoroughly.
Step 4: Cutting the Kernels
Using a sharp knife, hold each corn cob upright on a cutting board and carefully slice downward to separate the kernels from the cob. Repeat this process for all the corn cobs until you have a generous amount of kernels. You can adjust the size of the kernels based on your preference.
Step 5: Pre-treating for Optimal Preservation (Optional)
To retain the vibrant color of the sweetcorn, you can choose to pre-treat the kernels. In a bowl, mix approximately 1 tablespoon of lemon juice with 1 cup of water. Briefly soak the corn kernels in this solution for a few minutes. Lemon juice acts as an acidifier and helps to preserve the corn's color during the drying process. However, this step is optional and can be omitted if you prefer.
Step 6: Arranging on Dehydrator Trays
Spread the corn kernels in a single layer on dehydrator trays. Make sure the kernels are evenly spaced and not overlapping, easier said than done ! This allows for proper airflow and even drying.
Step 7: Dehydrating the Sweetcorn
Set your dehydrator to a temperature around 125°F (52°C) and let the sweetcorn dry for approximately 8-12 hours. The drying time can vary depending on the moisture content and the thickness of the kernels. Periodically check the kernels for dryness by removing a few and testing their texture. They should be hard, brittle, and free from any moisture.
Step 8: Testing for Dryness and Storage
Once the sweetcorn kernels are fully dehydrated, allow them to cool completely. Test for dryness by squeezing a few kernels between your fingers - they should feel hard and brittle with no moisture. If any kernels feel soft or damp, they need more drying time. Once properly dried, transfer the sweetcorn kernels to airtight containers, such as glass jars or vacuum-sealed bags, to prevent moisture.
Common questions asked with regards to dehydrating corn
Q: Can I skip the blanching step?
A: While it's not necessary, blanching is highly recommended for optimal preservation and food safety. It helps maintain the quality of the corn and extends its shelf life.
Q: How do I know when the corn is fully dehydrated?
A: The corn kernels should be hard, brittle, and free from any moisture. You can test their dryness by squeezing a few kernels between your fingers. If they feel soft or damp, they need more drying time.Just remember that you cant over dry in the dehydrator.
Q: What is the recommended drying time for corn in a dehydrator?
A: It typically takes around 8-12 hours to fully dehydrate corn in a dehydrator. However, the drying time may vary depending on the moisture content and thickness of the kernels.
Q: Can I use an oven instead of a dehydrator?
A: Yes, you can use an oven if you don't have a dehydrator. Set the oven to the lowest temperature with the door slightly ajar and spread the corn kernels on a baking sheet lined with parchment paper. Monitor them closely to ensure they don't over-dry, ie start looking brownish rather than yellow.
Q: How should I store dehydrated corn?
A: Transfer the fully dried corn kernels to airtight containers, such as glass jars or vacuum-sealed bags, to protect them from moisture and air. Store them in a cool, dark place away from direct sunlight.
Q: How long can I store dehydrated corn?
A: When properly stored, dehydrated corn can last for up to 5 years or even longer. However, for the best quality, it's recommended to use them within 1-2 years.
Q: How can I rehydrate the corn for use?
A: To rehydrate the corn, you can soak the kernels in water for a few hours or overnight until they regain their original texture and plumpness. Alternatively, you can add them directly to soups, stews, or other dishes with sufficient liquid for them to rehydrate during the cooking process.
Remember, practice and experimentation will help you achieve the desired results, and don't be afraid to adjust the process based on your preferences and experience. Lastly, don't be afraid of dehydrating; you have nothing to lose but a lot to gain.
