In this comprehensive guide, we’ll walk you through everything you need to know about blanching kale, from selecting the best kale to storing it properly after blanching. We’ll cover different blanching methods, provide detailed step-by-step instructions, and even share some delicious ideas for using your blanched kale. Get ready to unlock the full potential of this amazing superfood!
## Why Blanch Kale?
Before we dive into the how-to, let’s understand why blanching is such a beneficial technique for kale.
* **Tenderizes:** Blanching breaks down the cell walls of the kale, making it more tender and easier to chew. This is particularly important for tougher varieties like curly kale.
* **Reduces Bitterness:** The quick exposure to heat helps to remove some of the bitter compounds in kale, resulting in a milder, more palatable flavor.
* **Enhances Color:** Blanching intensifies the green color of kale, making it more visually appealing. This is due to the removal of air from the plant tissue.
* **Prepares for Freezing:** Blanching is a crucial step when freezing kale. It stops the enzymatic action that can cause loss of flavor, color, and texture during frozen storage.
* **Reduces Cooking Time:** If you’re planning to use kale in a dish that requires further cooking, blanching pre-cooks it slightly, reducing the overall cooking time.
* **Removes Surface Impurities:** The blanching process helps to cleanse the kale by removing dirt, debris, and any lingering pests.
## Choosing the Right Kale for Blanching
While you can blanch any type of kale, some varieties benefit more from the process than others. Here’s a quick overview of popular kale varieties and how they respond to blanching:
* **Curly Kale:** This is the most common type of kale, with tightly curled, dark green leaves. Curly kale can be quite tough and bitter, so blanching is highly recommended to tenderize it and mellow its flavor.
* **Lacinato Kale (Dinosaur Kale or Tuscan Kale):** Lacinato kale has long, narrow, dark green leaves with a slightly wrinkled texture. It’s more tender than curly kale, but blanching can still help to improve its texture and flavor, especially if you plan to use it in salads or soups.
* **Red Russian Kale:** This variety has flat, fringed, grayish-green leaves with reddish-purple stems. Red Russian kale is relatively tender and has a milder, slightly sweet flavor. Blanching is optional but can help to brighten its color and make it even more tender.
* **Baby Kale:** Baby kale is simply young kale leaves, usually a mix of different varieties. It’s very tender and has a mild flavor, so blanching is usually not necessary unless you’re planning to freeze it.
When selecting kale at the grocery store or farmer’s market, look for leaves that are firm, vibrant in color, and free from blemishes or yellowing. Avoid kale with wilted or damaged leaves.
## Preparing Your Kale for Blanching
Before you start blanching, it’s important to properly prepare your kale. Follow these steps:
1. **Wash Thoroughly:** Rinse the kale leaves under cold running water to remove any dirt or debris. Pay special attention to the areas where the leaves attach to the stem, as dirt can often accumulate there.
2. **Remove Tough Stems:** Kale stems can be quite tough and fibrous, so it’s best to remove them before blanching. You can do this by holding the stem in one hand and running your fingers along the leaf to strip it away. Alternatively, you can use a knife to cut the leaves away from the stem.
3. **Chop or Tear into Desired Size:** Depending on how you plan to use the blanched kale, you can chop it into smaller pieces or simply tear it into bite-sized pieces. If you’re planning to use it in a salad, smaller pieces are ideal. If you’re planning to use it in a soup or stir-fry, you can leave the leaves larger.
## Blanching Methods: Boiling vs. Steaming
There are two main methods for blanching kale: boiling and steaming. Both methods are effective, but they have slightly different advantages and disadvantages.
### Boiling Kale
Boiling is the most common and straightforward method for blanching kale. It’s quick, easy, and requires minimal equipment.
**Pros:**
* Fast and efficient
* Requires minimal equipment
* Evenly cooks the kale
**Cons:**
* Can leach out some nutrients into the water
* May result in slightly less vibrant color compared to steaming
### Steaming Kale
Steaming is a gentler method that helps to preserve more of the kale’s nutrients and color.
**Pros:**
* Preserves more nutrients than boiling
* Results in a more vibrant green color
* Maintains more of the kale’s natural flavor
**Cons:**
* Takes slightly longer than boiling
* Requires a steamer basket or insert
* Can be less even cooking if the kale is not spread out properly
## Step-by-Step Instructions for Blanching Kale
Now that you’ve chosen your preferred blanching method, let’s get started!
### Blanching Kale by Boiling
**Equipment:**
* Large pot
* Slotted spoon or tongs
* Large bowl filled with ice water
**Instructions:**
1. **Bring Water to a Boil:** Fill a large pot with water and bring it to a rolling boil. Make sure there’s enough water to completely submerge the kale.
2. **Prepare Ice Bath:** While the water is heating up, prepare an ice bath by filling a large bowl with ice and water. The ice bath is crucial for stopping the cooking process and preserving the kale’s color and texture.
3. **Add Kale to Boiling Water:** Once the water is boiling, add the prepared kale to the pot. Make sure not to overcrowd the pot, as this can lower the water temperature and result in uneven blanching. If necessary, blanch the kale in batches.
4. **Blanch for 2-3 Minutes:** Let the kale cook in the boiling water for 2-3 minutes, or until it turns a bright green color and becomes slightly tender. Stir the kale occasionally to ensure even cooking.
5. **Remove Kale and Plunge into Ice Bath:** Using a slotted spoon or tongs, quickly remove the blanched kale from the boiling water and immediately plunge it into the ice bath. This will stop the cooking process and prevent the kale from becoming overcooked and mushy.
6. **Cool Completely:** Let the kale cool completely in the ice bath for several minutes, or until it’s no longer warm to the touch.
7. **Drain and Dry:** Once the kale is cooled, drain it thoroughly and gently squeeze out any excess water. You can use a salad spinner or pat it dry with paper towels.
### Blanching Kale by Steaming
**Equipment:**
* Pot with a steamer basket or insert
