Is sweet-tasting raw kale normal? I just tried eating kale for the first time, raw, in a salad without any dressings, and to my surprise it did not taste bitter at all unlike descriptions of its taste that I've seen online. In fact it tasted a little sweet. Is it possible for raw kale to taste sweet? Did I buy a different variety of kale?

If it helps at all: I am in New Zealand, and my taste buds are usually extremely sensitive to bitterness.
I've found Kale to be less bitter in the traditional sense, and more like a Leafy broccoli.
