I am going to start making kale smoothies and wish to buy a couple bunches of kale at a time. Here's my thought - I was thinking of taking the kale, perhaps blending it with some roots/veggies at a high concentration (maybe adding some green tea or some water to the blender), then pouring this concentrated kale solution into ice cube trays. When it's time to make the smoothie, I would take a few of the "kale cubes" and blend it with, maybe orange juice or some other liquid. Does anyone have any better ideas for keeping kale fresh for a long time - and by long time, I mean around 2 weeks. Ideally, I would want a solution like the one I describe above - it's efficient and quick to make a smoothie doing it this way.
And one other question - does kale (or any veggies for that matter) lose nutrients when blended and frozen?
