Kale

Let me tell you about kale, and why it is not just another salad leaf.

Kale is a cabbage that never bothered to form a head. It just grows loose, open leaves, and you feel the difference the moment you pick one up: thick, ruffled, almost squeaky between your fingers. That toughness is exactly why you cannot treat it like lettuce. Raw, straight from the bag, it chews like paper. Rub it with oil and a little salt, press it with your hands for a minute or two, and you'll feel the leaf give, shrink a little, turn darker, start to taste like something you actually want to eat.

Choose kale by sight: leaves should stand upright, deep green, no yellow edges, no slimy patches. Smell it — fresh kale smells green and clean, nothing sour.

Some people say kale is only good raw, in smoothies and salads, because cooking "kills the nutrients." No! Cooking does cost kale some of its more delicate vitamins, true, but in return it gives you something raw kale never will. Braise it, throw it into soup, let it sit with onions and garlic in a pan — it turns mellow, the sharp bitterness fades. That misconception pushes people toward chewing raw, bitter, undressed kale once, deciding they hate it, and never buying it again.
