Why Freeze Kale

Why Freeze Kale

Kale is a nutritious and delicious leafy green that is packed with vitamins, minerals, and antioxidants. It is a versatile ingredient that can be used in a variety of recipes, from salads to smoothies to soups.

Additionally, frozen kale can be used in a variety of recipes, making it a convenient ingredient to have on hand.

One of the benefits of freezing kale is that it is an easy and cost-effective way to preserve this leafy green. Freezing kale requires minimal preparation and can be done using basic kitchen equipment.

Plus, frozen kale can be stored for several months, which means that you can enjoy this nutritious ingredient year-round.

Overall, freezing kale is an excellent way to preserve its nutrients and flavor. Whether you have an abundance of fresh kale that you want to preserve or want to have this nutritious ingredient on hand for future recipes, freezing is a simple and effective way to do so.

Choosing and Preparing Kale

Choosing and Preparing Kale

When it comes to choosing kale, there are two main options: the grocery store or the farmers’ market. While both options can provide fresh kale, there are some differences to consider.

Grocery Store vs Farmers’ Market

Grocery stores often offer pre-packaged kale that has been washed and trimmed. While this may be convenient, it can also mean that the kale has been sitting on the shelf for a few days.

On the other hand, farmers’ markets offer freshly picked kale that has not been pre-washed or trimmed. This means that it may require a bit more preparation, but it will also be fresher.

When choosing kale, look for leaves that are dark green and firm. Avoid any leaves that are yellow or wilted. If possible, choose kale with the stems still attached, as they can be used in recipes as well.

Prepping Fresh Kale

Before freezing kale, it is important to properly prep it. This involves washing and trimming the leaves. Here is a step-by-step guide:

  1. Fill a large bowl with cold water.
  2. Remove the kale leaves from the stems and discard the stems (or save them for later use).
  3. Place the leaves in the bowl of water and swish them around to remove any dirt or debris.
  4. Lift the leaves out of the water and place them in a colander or strainer to drain.
  5. Pat the leaves dry with a clean kitchen towel or paper towel.

Once the kale is prepped, it is ready to be frozen.

Freezing Process

Freezing Process

Freezing kale is a great way to preserve its nutrients and flavor for later use. Here are the steps to follow for an effective freezing process:

Blanching Kale

Blanching is a crucial step in the freezing process, as it helps to preserve the color, texture, and flavor of the kale. Follow these steps to blanch kale:

  1. Bring a large pot of water to a boil.
  2. While waiting for the water to boil, remove the kale leaves from the stems and rinse them thoroughly.

Flash Freezing

Flash freezing is a technique that helps to prevent the kale leaves from sticking together and forming clumps. Here’s how to flash freeze kale:

  1. Lay the blanched and dried kale leaves in a single layer on a baking sheet.
  2. Place the baking sheet in the freezer and freeze the kale leaves for 1-2 hours, or until they are completely frozen.
  3. Once the kale leaves are frozen, remove them from the baking sheet and transfer them to a freezer-safe bag or container.

Packing and Storing

Proper packing and storing will help to prevent freezer burn and keep the kale fresh for longer. Here are some tips for packing and storing frozen kale:

  1. Use freezer bags or containers that are specifically designed for freezing food.
  2. Remove as much air as possible from the bag or container before sealing it.
