this is a great idea, claire! thanks.
i have a load of kale that needs a use and i've run out of ideas for it.
how do you keep your leaves from unrolling?
I would think if you remove the stem and blanche the leaves first, and roll them like a cigar, not too tightly, they'd stay rolled (seam side down) and freeze well. I haven't tried using kale since I was trying to figure out what to do with the grape leaves and eat the kale almost daily from mid summar through the end of December (kale grows well in our garden). I put it on sandwiches, make pesto from it, etc.
Here in SE Ontario, we bank/mulch the kale with straw after a killing frost. Depending on the winter, we can harvest kale until the end of December, sometimes until the end of January. People who live in Nova Scotia and do this can eat it all winter--I am guessing your winters would be similar to those in NS. We get straw at the farm coop.
Kale chips will keep a long time and are YUMMY. But, if you can leave the kale in the garden, I would do that--it will go more or less dormant, but you can go out and pick it as you want, and don't have to store it.
I made curried creamed kale last week, topped with a FRESH fried egg, for lunch. It was very tasty now that we've had a killing frost because the kale is sweeter. I find kale in supermarkets is tough and bitter, not so with that which we grow.
IMO, kale is like eggplant in North America--under-appreciated. My friends in Denmark used to put the kale in the freezer for 30 minutes to draw out its sweetness. Might help supermarket kale--I haven't tried it but I do like kale better after the first frost. I basically use kale in place of spinach.
If you want to freeze it, blanche it for about 4 minutes, put in ice water, and then use a salad spinner and spin as much water out of it as possible and then squish it in a dish towel. Pack it in an ice cube tray. It is amazing how much kale you can pack into each "cube." Once frozen, toss the cubes in a zippie.
