How much kale is too much?

I have never (successfully) grown kale before this year. Last summer, I made a late-summer, direct-seeded effort, for naught. This summer, I started plants inside. After giving some to my daughter, I transplanted eight into my garden. And they have grown magnificently.

Then came the question of when to harvest. Many recommended picking off the outer leaves as they became big, letting more form from within, which is also how I harvest leaf lettuce for my salads. And it turns out, one may blanch and freeze both the leaves and stems, which I did last night, with the intention of using the former for soup and the latter for stock.

But then what? Some can go into salads and stirfry and smoothies. But still. That's a lot of kale for one person. Maybe I can leave the extra on my neighbors' porches, a hint of things to come after the inevitable zucchini-apocalypse.
