green juice in the juicer. The rest of the time, I use the blender! Much faster clean up when using the blender of course.
The blender yields a more fibrous juice, little more like a smoothie. But the fiber is an important part of vegetables' cancer-fighting arsenal. And if I get a tablespoon of really fibery stuff in the bottom of my glass I just throw it out. Removing the kale stems/stalks, and skimming the foam off with a spoon both help to remove some of the extra fiber :).
My favorite kale is Tuscan/Lacinato/Dinosaur kale. As with any juice, the fresher the better, so don't let this sit around-- drink right away or within a couple hours.
Tear off leaves from kale stems. Discard stems.
Push 1-2 C kale leaves into blender. Add 1-2 C water. Blend thoroughly on high.
Pour into drinking cups. I use a spoon to skim most of the foam off and discard it.
Optionally add a squeeze of lemon juice.
