What Are The Different Types of Kale?

While there are several varieties of kale, the following are some of the most common types:

  1. Curly Kale: Curly kale is the most recognizable and widely available variety. It has dark green curly leaves with a ruffled texture. Curly kale has a slightly bitter and peppery flavor and is often used in salads, stir-fries, soups, and smoothies.

Can Kale Be Eaten Raw?

Yes, kale can be enjoyed raw in salads or smoothies. However, some people find that massaging the leaves with a bit of oil or dressing can help to soften the texture and reduce bitterness, making it more palatable.

What Does Massaging Kale Mean?

Massaging kale refers to a technique used to soften the texture and enhance the flavor of raw kale leaves. Raw kale can sometimes be tough and slightly bitter, but massaging helps break down the fibrous structure and makes it more enjoyable to eat. Here's how to massage kale:

  1. Remove the tough stems: Start by removing the tough stems from the kale leaves. Hold the stem with one hand and use the other hand to strip the leaves off.

  2. Tear or chop into bite-sized pieces: Tear or chop the kale leaves into bite-sized pieces. This allows for easier massaging and eating.

  3. Add oil and salt (optional): Drizzle a small amount of oil, such as olive oil, over the kale leaves. This step is optional but can help to soften the kale further and add some flavor. Sprinkle a pinch of salt over the leaves as well, which can help draw out moisture and reduce bitterness.

  4. Massage the kale: Use your hands to massage the kale leaves gently. Grab handfuls of kale and squeeze and knead them for a few minutes. The goal is to tenderize the leaves and break down their fibrous structure. You will notice the kale leaves become darker in color and softer in texture as you massage.

  5. Let it rest: After massaging, let the kale rest for a few minutes. This allows the leaves to further soften and absorb any flavors from the oil and salt.
