How to Dehydrate Kohlrabi: A Unique Ingredient

Introduction

Kohlrabi, often referred to as the “turnip cabbage,” is a unique cruciferous vegetable that has been gaining popularity in recent years. Its distinctive bulbous shape and vibrant colors—ranging from pale green to deep purple—make it a visually appealing addition to any dish. The taste of kohlrabi is mild and slightly sweet, with a crisp texture reminiscent of broccoli stems or cabbage hearts. Nutritionally, kohlrabi is a powerhouse, packed with vitamins C and B6, fiber, potassium, and antioxidants.

Dehydration is a fantastic method of food preservation that allows you to enjoy seasonal produce like kohlrabi well beyond its harvest. By removing moisture, dehydration extends the shelf life of the vegetable while concentrating its flavor and nutritional benefits. In this article, we will explore the various benefits of dehydrating kohlrabi, how to prepare it for dehydration, different methods for drying, storage options, and exciting ways to incorporate dehydrated kohlrabi into your cooking.

Section 2: Preparing Kohlrabi for Dehydration

Selecting Fresh Kohlrabi

Choosing the right kohlrabi is crucial for successful dehydration. Look for:

• Size: Smaller kohlrabi bulbs tend to be more tender and flavorful.
• Color: Choose vibrant bulbs, whether green or purple, avoiding any that appear dull or have brown spots.

1. Wash the kohlrabi under cold running water to remove dirt and debris.
2. Use a vegetable peeler or knife to carefully remove the tough outer skin, exposing the tender flesh inside.

Cutting Techniques

Uniformity in cutting is essential for even drying. Here are recommended cutting methods:

• Slices: Thinly slice kohlrabi into rounds for chips or salads.
• Cubes: Cut into small cubes for stews and soups.
• Julienne: Shred the kohlrabi into strips for stir-fries or slaws.

Section 3: Methods of Dehydrating Kohlrabi

3.1 Using a Dehydrator

Dehydrating kohlrabi in a dehydrator is one of the easiest and most efficient methods. Here’s what you need:

• Food dehydrator
• Cutting board and knife
• Storage containers for the dehydrated kohlrabi

Follow these steps for dehydrating kohlrabi:

1. Arrange the kohlrabi pieces on the dehydrator trays, ensuring they are not overlapping.
2. Set the dehydrator temperature to 125°F (52°C).
3. Dehydrate for 6-8 hours, checking for doneness. The kohlrabi pieces should be crisp and break easily.

3.2 Oven Drying

If you don’t have a dehydrator, you can use your oven. Here’s what you’ll need:

• Oven
• Baking sheets lined with parchment paper
• Cooling rack

Here’s how to do it:

1. Preheat your oven to 140°F (60°C).
2. Spread the kohlrabi pieces on baking sheets, ensuring they are in a single layer.
3. Place the baking sheets in the oven and leave the door slightly ajar for air circulation.
4. Dry for 4-6 hours, checking periodically until the kohlrabi is dry and crispy.

3.3 Air Drying (For the adventurous)

If you’re feeling adventurous and live in a suitable climate, you can try air drying:

• Ideal climate: Warm, dry conditions with low humidity are best.
• Hanging: Use a string or wire to hang kohlrabi pieces in a well-ventilated area, spaced apart to allow airflow.

Estimated drying time can vary greatly but generally falls between 1-3 days, depending on the temperature and humidity.

Section 4: Storing Dehydrated Kohlrabi

Storage Options

Once dehydrated, storing kohlrabi correctly is essential for maximum longevity:

• Glass Jars: Ideal for short-term storage. Keep them in a cool, dark place.
• Vacuum-Sealed Bags: Best for long-term storage as they reduce air exposure.

Shelf Life

Here’s a general idea of the shelf life for different storage methods:

• Glass jars: 6 months
• Vacuum-sealed bags: 1-2 years
