Freezing Kale for Long-Term Storage
Kale is a nutritious leafy green vegetable that can easily be preserved by freezing. Freezing kale is an excellent way to extend its shelf life and have a ready supply of this healthy ingredient on hand. Here are some steps to follow when freezing kale for long-term storage:
1. Washing and Preparing the Kale
Start by washing the kale thoroughly under cold running water to remove any dirt or debris. Once clean, remove the tough stems and tear the leaves into smaller, more manageable pieces.
2. Blanching the Kale
Blanching is an important step in the freezing process as it helps to preserve the color, flavor, and texture of the kale. Bring a large pot of water to a boil and add the kale leaves. Let them cook for 2 minutes, then transfer them to an ice bath to cool rapidly and stop the cooking process.
