There are two kinds of kale you'll usually find at the supermarket.
One is curly kale:
The other is lacinato kale, also called Tuscan kale, cavolo nero, or dinosaur kale (dino for short):
Curly kale is fibrous and grassy tasting, so it's not the *best* for salads, unless you really love chewing.
In general, lacinato kale works better.
First things first: Cut the ribs out of the leaves.
Now, you can rough-chop the kale leaves...
...or you can "chiffonade" them, which means slice them into thin ribbons.
To slice them into ribbons, use this great trick: Stack and roll up a bunch of leaves:
Then, slice through the roll:
Chiffonade kale makes beautiful salads.
Also, it's best if you're making a grain-based salad with kale.
Once you've sliced the kale, let it sit with a little oil and salt for about half an hour before mixing with other ingredients and dressing.
Choosing the right dressing makes a huge difference.
