From Kathleen Purvis’ blog I’ll Bite: obsbite.blogspot.com:
If you stick close to a local diet, that means lots of kale in the winter. I’m always seeking new kale variations, and I started seeing descriptions of a new technique recently:
Rubbed kale, sometimes called massaged kale. Seriously – you toss raw kale with olive oil, lemon juice and salt. And then you rub it: Knead it, squeeze it, scrub it between your palms. Do that for at least 2 minutes and the kale breaks down, softens and takes on a silky texture.
Yes, you have to rub it after you add the oil, salt and an acid. If you just rub the bare leaves, it won’t get all that soft.
After you soften the leaves (and wash your hands), toss the kale with a few more ingredients and end up with a terrific winter salad. You can add almost anything. The salad keeps a day or so in the refrigerator.
