Red Kale
Red kale, with its purple-tinged leaves, adds visual variety to dehydrated kale mixes. It has a similar taste to curly kale but with a slightly more robust flavor. The red pigments in this variety indicate high levels of anthocyanins, powerful antioxidants.
When dehydrated, red kale maintains much of its color, creating visually appealing kale chips. Its leaves are slightly tougher than other varieties, which can result in a crunchier texture when dried.
Red kale works well for both chips and powder. It’s particularly striking when mixed with green varieties in dehydrated kale blends. This type is rich in vitamin C and iron, nutrients that are largely preserved in the dehydration process.
Preparing Kale for Dehydration
Proper preparation is crucial for achieving crispy, flavorful dehydrated kale. The process involves cleaning, trimming, and optional seasoning to enhance taste and texture.
Cleaning and Trimming
Start by thoroughly washing the fresh kale leaves under cool running water. Remove any dirt or debris clinging to the leaves. Gently pat the kale dry with clean kitchen towels or use a salad spinner to remove excess moisture.
Next, remove the tough center stems from each kale leaf. These stems can be bitter and don’t dehydrate well. Tear or cut the leaves into bite-sized pieces, about 2-3 inches in size.
For optimal results, choose fresh, crisp kale leaves. Avoid using wilted or yellowing leaves, as they may not dehydrate evenly.
Seasoning Options
While plain kale chips are delicious, seasoning can elevate the flavor profile. Toss the kale pieces with a light coating of olive oil to help seasonings adhere and promote crispiness.
Popular seasoning combinations include:
- Sea salt and nutritional yeast for a cheesy flavor
- Garlic powder and onion powder for a savory taste
- Chili powder and cayenne pepper for a spicy kick
Mix your chosen seasonings in a small bowl before sprinkling over the oiled kale. Massage the seasoning into the leaves gently to ensure even distribution.
Remember to use seasonings sparingly, as flavors intensify during the dehydration process. Start with small amounts and adjust to taste in future batches.
Using a Dehydrator for Kale
A food dehydrator offers an efficient method for drying kale. This process preserves the nutritional value while creating crispy, shelf-stable kale chips or powder.
Setting Up the Dehydrator
Clean and dry the dehydrator trays thoroughly before use. Adjust the temperature setting to 135°F (57°C) for optimal kale dehydration. Ensure proper air circulation by spacing the trays evenly.
Place a liner on each tray to prevent small kale pieces from falling through. Arrange kale leaves in a single layer on the trays, avoiding overlap. This arrangement allows for even drying and prevents moisture buildup.
For whole leaves, remove thick stems before placing on trays. Smaller pieces dry faster and more evenly. Consider cutting kale into uniform sizes for consistent results.
Dehydrating Kale in a Food Dehydrator
Start the dehydrator and set the timer for 4-8 hours. Drying time varies based on kale thickness and desired crispness. Check progress every 2 hours, rotating trays if necessary for even drying.
Kale is properly dehydrated when it easily crumbles between fingers. Allow dried kale to cool completely before storage. This step prevents condensation and maintains crispness.
Store dehydrated kale in airtight containers or vacuum-sealed bags. Keep in a cool, dark place for maximum shelf life. Properly dried and stored kale can last up to 6 months.
For kale powder, crumble dried leaves and pulse in a food processor until fine. Use as a nutrient-rich addition to smoothies, soups, or baked goods.
Other Methods of Dehydrating Kale
Oven drying and air drying offer alternative methods for dehydrating kale without specialized equipment. These techniques can be easily implemented at home using common household items.
Oven Drying
Oven drying kale is a convenient method for those without a food dehydrator. Preheat the oven to its lowest setting, typically around 170°F (75°C). Wash and thoroughly dry the kale leaves, then remove the stems and tear into bite-sized pieces.
Arrange the kale in a single layer on baking sheets lined with parchment paper. Place the sheets in the oven, leaving the door slightly ajar to allow moisture to escape. This process usually takes 2-3 hours.
Check the kale every 30 minutes, rotating the trays for even drying. The kale is ready when it’s crisp and crumbly to the touch. Let it cool completely before storing in airtight containers.
Air Drying
Air drying kale is a traditional method that requires no electricity. Start by washing the kale and patting it dry. Leave the leaves whole or tear them into large pieces.
Tie the kale stems together in small bundles using kitchen twine. Hang these bundles in a warm, dry, well-ventilated area away from direct sunlight. A covered porch or airy kitchen can work well.
The drying process typically takes 2-3 weeks. Check the kale regularly for signs of mold. Once the leaves are crisp and crumbly, they’re ready to be stored. Crumble the dried kale into airtight containers for long-term storage.
Storing Dehydrated Kale
Proper storage is crucial for maintaining the quality and extending the shelf life of dehydrated kale. Cool, dry conditions and airtight containers are key to preserving its nutritional value and crisp texture.
Using Airtight Containers
Store dehydrated kale in containers that prevent air and moisture from entering. Glass jars with tight-fitting lids or vacuum-sealed bags are excellent options. Ensure the kale is completely cool before storing to prevent condensation.
For added protection, add a food-grade silica gel packet to absorb any residual moisture. Label containers with the date of dehydration for easy tracking.
Consider storing smaller portions in separate containers. This minimizes air exposure each time you open the container, helping maintain freshness for longer periods.
Shelf Life Considerations
When stored properly, dehydrated kale can last 6-12 months. Keep containers in a cool, dark place like a pantry or cupboard. Avoid areas prone to temperature fluctuations or direct sunlight.
Check stored kale periodically for signs of moisture or mold. If you notice any off-odors or changes in appearance, discard the batch.
