Kale goes by another name, one much more dashing, especially in Italian. Cavolo Nero, black cabbage, may not evoke superhero status, but it's close. Kale does seem invincible and it's known to make the eater more so, too. It's also called dinosaur kale (also called lacinato), maybe because its leaves look like the back of a lizard. Those thin knobby leaves squeak. Do not confuse cavolo, accent on the first syllable, with cavallo, accent on the second, or you'll be ordering black horse, and in certain parts of the world will find it. Hearty and good for the spirit. I like soaked and cooked cannellini better than canned ones.
